As the birth-dose for hepatitis B (HBV) increases, sexual transmission is the most common mode of transmitting hepatitis B among unvaccinated adults. A research study, “Evaluating the independent influence of sexual transmission on HBV infection in China: a modeling study” evaluated the independent impact of sexual transmission on hepatitis B. This blog will give a summary of the results of the study, prevention tips, and future recommendations.
Summary of Research Study
The researchers of this study developed an age- and sex-specific discrete model at the population level to evaluate the influence of sexual transmission on HBV infection in China. They found that in 2014, due to sexual transmission, the total number of chronic HBV infections in people aged 0–100 years increased by 292,581 people! That year, due to sexual transmission, there were 189,200 new chronic infections among men and 103,381 new chronic infections among women. In 2006, sexual transmission accounted for 24.76% (male: 31.33%, female: 17.94%) of acute HBV infections in China and in 2014, sexual transmission accounted for 34.59% (male: 42.93%, female: 25.73%) of acute HBV infections in China. These statistics demonstrate that acute HBV infections due to sexual transmission increased by 10% and 8% respectively from 2006-2014.
However, researchers found that if the condom usage rate increased by 10% annually starting in 2019, then compared with current practice, the total number of acute HBV infections from 2019 to 2035 would be reduced by 16.68% (male: 21.49%, female: 11.93%). The HBsAg prevalence in people aged 1–59 years in 2035 would be reduced to 2.01% (male: 2.40%, female: 1.58%).
Prevention and Harm Reduction Strategies During Sex
Practicing safe sex is can be a great way to prevent the transmission of hepatitis B. Condoms are an effective way to prevent the transmission of hepatitis B during intercourse. Sometimes during sex, people like to use personal lubricants. When using condoms it is important to remember to only use silicone or water-based lubricant. Oil-based lubricants increase the chance of ripping or tearing the condom. It is highly recommended if someone is living with hepatitis B to have sex with a condom, however, if you are having sex without a condom, certain sexual activities are far more efficient at spreading hepatitis B than others. Oral sex appears to have a lower rate of hepatitis B transmission than vaginal sex. Anal sex carries a very high risk of transmission because tears in the skin can occur during penetration, allow more transmission routes for the virus.
Recommendations
If you have never been vaccinated for hepatitis B, it is recommended that you receive the vaccination. The hepatitis B vaccine is a safe and effective vaccine that is recommended for all infants at birth and for children up to 18 years. Since everyone is at some risk, all adults should seriously consider getting the hepatitis B vaccine for lifetime protection against preventable chronic liver disease. The hepatitis B vaccine is also known as the first “anti-cancer” vaccine because it prevents hepatitis B, the leading cause of liver cancer worldwide.
If you think you might be at increased risk for hepatitis B infection, is also recommended you get tested for hepatitis B. Hepatitis B is known as the” silent” infection, meaning you could be infected with the virus and not show symptoms that can cause long-term liver damage. If you have not been tested for hepatitis B and would like to know your status, you should get in contact with your primary care provider. Your physician should order a panel of three blood tests for the hepatitis B panel:
HBsAg (hepatitis B surface antigen)
Anti-HBs or HBsAb (hepatitis B surface antibody)
anti-HBc or HBcAb (hepatitis B core antibody)
The results of all 3 blood test results are needed in order to make a diagnosis. Be sure to request a printed copy of your blood tests so that you fully understand which tests are positive or negative, and what your hepatitis B status is.
If you know you have had unprotected sexual intercourse with someone living with hepatitis B, there is something called post-exposure treatment. If an uninfected, unvaccinated person – or anyone who does not know their hepatitis B status – is exposed to the hepatitis B virus through contact with infected blood, a timely “postexposure prophylaxis” (PEP) can prevent infection and subsequent development of chronic infection or liver disease. This means a person should seek immediate medical attention (within 72 hours of exposure) to start the hepatitis B vaccine series. In some circumstances, a drug called “hepatitis B immune globulin” (HBIG) is recommended in addition to the hepatitis B vaccine for added protection.
The hepatitis B virus can cause an acute (lasting less than 6 months) or chronic (lifetime) infection. Chronic infection occurs in 90% of infants infected through mother-to-child transmission at birth; and about 50% of children will develop a chronic infection if exposed to the virus between 1 and 5 years of age. Those infected as adults are much less likely (<5%) to develop a chronic infection. Left untreated, hepatitis B can progress to cirrhosis and other serious liver diseases like liver cancer. This blog will talk about mother-to-child (perinatal) transmission and commonly asked questions about perinatal transmission.
Transmission of Hepatitis B from Mother to Child
Globally, the most common route of transmission is mother-to-child. Some people might think the hepatitis B virus is transmitted genetically, but this is NOT true. Hepatitis B is a virus that can be transmitted from a mother to her child because of the blood exchange that happens during childbirth. The great news is that we can prevent mother-to-child transmission! If a pregnant woman tests positive for hepatitis B infection, then her newborn must be given proper prevention immediately after birth in the delivery room, clinic or bedside:
first dose (called “birth dose”) of the hepatitis B vaccine
one dose of the Hepatitis B Immune Globulin (HBIG).*
*HBIG is recommended by U.S. CDC. HBIG is not recommended by WHO and may not be available in all countries. What is most important is to make sure the hepatitis B vaccine birth dose is given as soon as possible!
If these two medications are given correctly, a newborn born to a mother with hepatitis B has a 95% chance of being protected from a hepatitis B infection. You must make sure your baby receives the remaining shots of the vaccine series according to schedule to ensure complete protection.
And there is more good news – if a pregnant woman with hepatitis B has a high viral load during pregnancy, it is recommended that she take antiviral therapy during her third trimester, which will further reduce the risk of mother-to-child transmission. If you are pregnant and have hepatitis B, talk to your doctor about testing your HBV DNA level, and starting antiviral treatment if it is elevated. There are WHO guidelines for managing hepatitis B infection among pregnant women, which your doctor can use to guide your care.
Commonly Asked Questions About Perinatal Transmission
I am pregnant, should I be tested for hepatitis B?
ALL pregnant women should be tested for hepatitis B. Testing is especially important for women who fall into high-risk groups such as health care workers, women from ethnic communities or countries where hepatitis B is common, spouses or partners living with an infected person, etc. If you are pregnant, be sure your doctor tests you for hepatitis B before your baby is born, ideally as early as possible during the first trimester.
I have hepatitis B and I am pregnant, what should I do?
You already know your hepatitis B status – this is a great first step! The next thing you should do is tell your medical provider who should perform additional laboratory testing, including HBV DNA level (viral load), and should check to see if there is evidence of cirrhosis.
All pregnant women who are diagnosed with hepatitis B should be referred to care with a knowledgeable doctor. Some may require continued treatment with an antiviral, many will not. All women with hepatitis B need regular monitoring throughout their life since hepatitis B infection and the health of the liver can change over time.
Can I transmit hepatitis B to my baby when I am breastfeeding?
*Especially if your baby has received the hepatitis B vaccine birth dose, the benefits of breastfeeding outweigh any potential risk.*
Can I prevent my baby from contracting hepatitis B?
Yes! In all cases, it is very important that your obstetrician (or provider who will be delivering your baby), and your newborn’s pediatrician, are aware of your hepatitis B status to ensure that your newborn receives the proper vaccines at birth to prevent a lifelong hepatitis B infection and that you receive appropriate follow-up care.
Should I continue to see a doctor after I give birth?
Yes! Women who have hepatitis B should be closely monitored for 6 months after delivery whether they have been prescribed antivirals are not. This will ensure there are no dangerous elevations in liver enzymes, which can indicate liver damage (ALT flares). For most women whose follow-up testing shows no signs of active disease or cirrhosis, your physician will recommend regular monitoring with a liver specialist (hepatologist) or doctor with experience managing the care of people with hepatitis B.
World Health Organization Recommendations
In 2020, The World Health Organization released two new recommendations for the prevention of mother-to-child transmission of hepatitis B.
In addition to the series of hepatitis B vaccinations (including the first dose within 24 hours of birth), WHO now recommends that pregnant women testing positive for HBV infection (HBsAg positive) with an HBV DNA viral load threshold of ≥5.3 log10 IU/mL (≥200,000 IU/mL) receive tenofovir prophylaxis; the preventive therapy should be provided from the 28th week of pregnancy until at least birth.
In settings where HBV DNA testing is not available, WHO now recommends the use of HBeAg testing as an alternative to determine eligibility for tenofovir prophylaxis for the prevention of mother-to-child transmission of HBV This is because some settings have poor access to tests that quantify an individual’s HBV viral load and determine whether a pregnant woman would be eligible for preventive treatment or prophylaxis. This is especially the case in low-income settings or rural areas where many antenatal care visits take place.
Are you a member of the African diaspora in the United States? Do you work for an organization that serves these communities? We would love for you to join CHIPO – the Coalition Against Hepatitis for People of African Origin! CHIPO is a national community coalition, co-founded and led by the Hepatitis B Foundation. Our members include a variety of individuals and organizations from all over the country, who are interested in and focused on addressing the high rates of hepatitis B among African communities in the US., which are disproportionately affected by hepatitis B and liver cancer. In some parts of the country, rates of chronic hepatitis B infection in African communities are estimated to range between 5 and 15% of people.
The purpose of CHIPO is to provide a space for an open exchange of ideas, best practices, and information about how to dismantle some of the many barriers that stand in the way of preventing, diagnosing, and treating chronic hepatitis B infection, and preventing liver cancer, in African immigrant communities. These barriers include a lack of disease awareness, high rates of stigma, limited access to healthcare and services, and the silent nature of the disease, which often does not present any symptoms until significant liver damage has occurred – a process which could take years or even decades. As a result, most African community members who have hepatitis B DO NOT KNOW that they are infected. This puts them at much greater risk for premature death from cirrhosis or liver cancer.
CHIPO, meaning “gift” in the Shona language, aims to disseminate accurate information about hepatitis B transmission, prevention, and treatment among community members, healthcare providers, and organizational leaders, and to improve the national capacity to raise hepatitis B awareness, testing, vaccination, and linkage to care among highly affected African communities. CHIPO also works to ensure that African immigrant communities are represented in HBV discussions and programs regionally and nationally. This is achieved through advocacy and the development of national and local partnerships. We currently have over 35 coalition partners around the U.S., dedicated to addressing viral hepatitis in African communities.
The activities of CHIPO are many and diverse. They include bimonthly virtual meetings, which often center around a presentation by a coalition member about measures or interventions that have been undertaken or research that has been done to achieve one of CHIPO’s objectives – namely improving awareness about and access to hepatitis B information, screening, vaccination, and linkage to follow-up care. Other activities include educational community events and presentations; supporting the design and implementation of initiatives to help accomplish CHIPO’s goals, such as the CDC Know Hepatitis B campaign (discussed below) and a recent grant from Bristol Myers Squibb to raise awareness about liver cancer and understanding about the link between hepatitis B and liver cancer in African immigrant communities; and promoting the work of coalition members locally and nationwide.
An example of a project for which CHIPO provided great support and guidance was the production of the first nationally available hepatitis B educational resources, specifically for African populations. Created in collaboration with the Centers for Disease Control and Prevention (CDC), these materials are part of a train-the-trainer-based model, and include a suite of materials, including a downloadable presentation on hepatitis B for community health workers, a printable flip chart for direct community education, and supporting fact sheets and resources. The presentation and flip chart have also been translated into Amharic, Arabic, French, and Swahili.

Does this work sound interesting to you? Would you like to work with us to achieve lower rates of hepatitis B and liver cancer in African immigrant communities through increasing awareness, screening, vaccination, and linkage to care? Join us! Anyone is welcome to join CHIPO – contact the coordinator to get involved. We hope to see you on our next call!
Hep B United is very pleased to report that the eighth annual (and first virtual) Hep B United Summit was a great success! With over 200 attendees from around the US, the summit brought together partners – both new and familiar – to discuss and collaborate on the successes and challenges of the past year, and strategies to move forward toward the elimination of hepatitis B.
The theme of this year’s summit was “Standing Up for Hepatitis B: Creative Collaborations to Amplify Awareness, Access, and Equity.” The event included many exciting sessions on topics such as progress toward a hepatitis B cure; strategies for providing hepatitis B services in the time of COVID-19; federal updates on hepatitis B; methods for incorporating hepatitis B into viral hepatitis elimination planning efforts at state and local levels; the path to universal adult hepatitis B vaccination; expansion of hepatitis B outreach in non-traditional settings, such as pharmacies, harm reduction centers, and correctional facilities; the pandemic of structural racism and how to bridge gaps in healthcare; and elevating the patient voice to move elimination efforts forward. The event included a poster session with over 20 submissions from presenters around the country, ranging from medical students to organizational partners, and covering a diverse and comprehensive array of topics related to hepatitis B.
The virtual platform offered a dynamic and engaging experience, with opportunities for networking, game participation, social media involvement, and learning. The Summit concluded with an award ceremony in which nine Hepatitis B Champions and a Federal Champion were honored for their efforts and dedication to hepatitis B advocacy, awareness, prevention, and elimination efforts over the past year.
As in previous years, the Summit provided an opportunity for colleagues to gather and to exchange innovative and creative ideas that will help to advance hepatitis B elimination and elevate hepatitis B as an issue deserving of widespread national attention. Recordings of the Summit are available on Hep B United’s YouTube channel – check them out today!
On Monday September 21st, a virtual celebration was held in honor of the sixth anniversary of National African Immigrant and Refugee HIV and Hepatitis Awareness (NAIRHHA) Day. This day, which itself is commemorated on September 9th, was created to build awareness and dismantle stigma around HIV and viral hepatitis in African immigrant and refugee communities. It takes place in September because this is the month that has been designated as National African Immigrant Month (NAIM) in the United States to celebrate the diverse and remarkable contributions African immigrants have made to enrich the United States, in spheres ranging from sports to writing to politics.
The virtual celebration that occurred last Monday included a discussion of the history of NAIRHHA Day and how it came to exist in its present form, a conversation with a hepatitis B advocate who is living with the disease, discourse about the importance of NAIRHHA Day on the national level and implications for making it a federally recognized day, and trivia questions about HIV and hepatitis B.
History of NAIRHHA Day: The Journey from 2014 to Present
Moderator: Chioma Nnaji, MPH, MEd, Program Director, Multicultural AIDS Coalition
Panelists: Augustus Woyah, Program Officer for Minority AIDS Initiative, Maryland Department of Health
Amanda Lugg, Director of Advocacy and LGBTQ Programming, African Services Committee
The idea for NAIRHHA Day was first conceived in 2006 at a convening of the Ethiopian Community Development Corporation in Washington, DC, at a session sponsored by Office of Minority Health about HIV in African immigrant communities. Conferences started to occur, primarily in the Northeast, although there was also interest in Atlanta and Seattle. It seemed that an opportunity had finally become available for advocates, researchers, and providers to all come together and focus on data collection, community mobilization, and policy work around HIV and viral hepatitis in African immigrant communities. The African National HIV/AIDS Alliance was established in 2010 and awareness days started in 2012 (Augustus played a large role in this). In 2014, Chioma Nnaji became connected to Sylvie Bello, the Executive Director of the Cameroonian Association in Washington, DC, and they, along with Amanda and Augustus, worked to get NAIRHHA Day off the ground. Chioma has largely spearheaded efforts to have NAIRHHA Day recognized nationally.
In terms of some of the challenges that have and continue to exist around NAIRHHA Day, obtaining community leadership and organizational buy-in, as well as national attention, are at the forefront. Social media and other digital platforms have been widely used in order to amplify the cause and try to obtain federal recognition. Additionally, maintaining relationships with government agencies has been quite difficult and has become a clash of visions of sorts. There is a strong belief that NAIRHHA Day should be a community-driven effort, but government agencies often have their own priorities, which can be distinct from those of the community and grassroots organizers. This is not to discount the government and organizational partners that are still involved, however, including NASTAD, the Hepatitis B Foundation, CHIPO, CHIPO-NYC, and Africans for Improved Access at the Multicultural AIDS Coalition. Another challenge has been reinforcing the distinction between African immigrant and African American communities and not treating the Black community as a monolith. Drawing this distinction in both data and policy remains difficult, thus often rendering African immigrant communities invisible.
When pondering what areas could use improvement going forward, a number of different items were considered. These included incorporating COVID-19 into the conversation, along with viral hepatitis and HIV; addressing social and environmental determinants of health that lead to the over-prevalence of both infectious and non-communicable diseases in minority, and particularly African immigrant communities; adhering to the primary goal of community mobilization and including advocates and researchers to influence policy that provides linguistically and culturally appropriate services that address the most pressing issue of stigma; securing national attention; and obtaining resources. It is critical to remember that advocacy never ends, the need to magnify work and amplify voices is always present, there is no room for complacency, and there exists intersectionality in all issues (social and health justice are all-encompassing).
#justB Storyteller Interactive Discussion
Moderator: Farma Pene, Community Projects Coordinator in Viral Hepatitis Program, New York City Department of Health & Mental Hygiene
#justB Storyteller: Bright Ansah
In this session, Bright spoke about his experience with living with hepatitis B, including his diagnosis, treatment, and communication with his family. He spoke about being able to put a face to hepatitis B, which has helped many people and also allowed him to build strong relationships with a broader community. Bright found out about his status in 2014 and initially felt very lost. The first couple of years were a big struggle, as he did not want to worry his family and it took a while for him to come to peace with his diagnosis. This peace eventually came from a lot of extensive research, after which he found out that hepatitis B is not a death sentence and can be managed very well. He then started to think about what he could do to prevent someone else from becoming “a statistic.”
When asked what message he would share with newly diagnosed people, Bright stated that stress and anxiety are normal, but you are not alone. Every day, people find out they are infected. Bright has given his contact information to many different people and he emphasized the incredible importance of having a support system in place. When asked about how he overcame stigma and barriers, Bright replied that the biggest barrier is the mental hurdle. It took him about two years to not feel overwhelmed. Bright does still struggle with feeling rejected from clinical trials and finds this very frustrating – he still feels like he is being punished for having chronic hepatitis B.
The best advice that Bright can offer is to always be your own advocate and do your own research. If the first doctor or liver specialist that you find does not take you seriously or you feel that they are not doing enough for you, you do not need to stay with them and you can absolutely find another doctor. Bright went through this process himself and eventually found a doctor he likes at Johns Hopkins, through a friend of his. This can be a challenge with language barriers, but there are organizations that can help and there is a Specialist Directory tool on the Hepatitis B Foundation website, a resource that Bright stated he found very helpful, along with the website of the National Institutes of Health (NIH). Farma reiterated that the HBF website is a great place to visit to understand lab results in plain language, and offers a good collection of resources for family and community members of people living with hepatitis B. Bright finds that the most important questions to ask are: What exactly is your status and viral load? What should reasonable expectations for your life and health be? Is treatment appropriate and if so, which one? It is crucial to establish mutual respect with your doctor, and to iterate what expectations you have for your doctor as well. The most important messages are: Reach out. Ask questions. Stand up for yourself. You are not alone.
The Important Role that NAIRHHA Day Plays from a National and Policy Prospective
Moderator: Chioma Nnaji, MPH, MEd, Program Director, Multicultural AIDS Coalition
Panelists: Boatemaa Ntiri-Reid, JD, MPH, Hepatitis Director, NASTAD
Jennease Hyatt, Community Liaison for Boston/New England, GILEAD
The final conversation focused on why NAIRHHA Day should become a nationally recognized holiday. VIral hepatitis is the seventh leading cause of death globally. Nineteen million African adults are living with hep C, and 5-8% are living with hep B. Hep B and HIV need to be considered part of the health portfolio of African immigrants, with care taken that this does not compound stigma. NAIRHHA Day is really an opportunity to focus on this community specifically. You get things done by doing them yourselves and we are who we’ve been waiting for.
There is a strong need for a multi-faceted approach to this work and for local, state, and national partnerships. African immigrants need to be at the forefront of the HIV/AIDS conversation. In Massachusetts specifically, over half of new HIV infections are in immigrant communities: These communities need to be leading the conversation. In terms of the role that government agencies play in NAIRHHA day, this needs to be more than a supportive role. We need to talk about novel approaches. We know that there are healthcare disparities. We need to consider how to use funding to build capacity and engagement, and make sure this work moves forward. This should include counting in community members and small businesses and bringing people to the table who are not usually there. The community really wants to be engaged. Promoting testing and awareness at soccer games, for example, is a great idea. We need strong partnerships and leadership from the beginning and to determine different approaches and thus different outcomes. Community members are the experts and we need to treat them as such.
Across the country, there are jurisdictions that have a prevalence of 40,000 people living with hepatitis in a state and viral hepatitis staff have teams of 1-7. Local and state health departments have more of a role to play. CDC publishes a list of viral hepatitis coordinators by state. It would be great to close the gap with them and discuss more about what they are doing generally and how to get them more involved in NAIRHHA Day specifically. In thinking about a vision for NAIRHHA Day next year, thoughts included that everyone who serves African immigrant communities (including health centers and multi-service organizations) needs to see themselves as part of the solution. Additionally, federal representation should be part of NAIRHHA Day next year.
Trivia and Conclusion
The event concluded with trivia questions about HIV and hepatitis B prevention, testing, and treatment. Amazing music was provided by DJ WhySham and Laura O (@LauraO_TV) served as an excellent moderator. Thanks to everyone who participated and we look forward to another wonderful event next year!
To discuss the latest advances in addressing viral hepatitis and other liver diseases in Africa, there will be a virtual Conference on Liver Disease in Africa (COLDA) from September 10th to 12th, 2020. COLDA is organized by Virology Education on behalf of the organizing committee led by Drs. Manal Al-Sayed, Mark Nelson, and Papa Saliou Mbaye. This virtual conference will gather clinicians, patients, other healthcare professionals, and policymakers from African regions, with international experts to support and exchange innovative ideas and knowledge about liver disease. The conference will consist of lectures discussing viral hepatitis infections, hepatitis co-infections, non-viral hepatitis-related infections, non-infectious induced liver disease, hepatocellular carcinoma, and end-stage liver disease. This virtual conference is important for addressing viral hepatitis since fewer than 1 in 10 people in Africa has access to testing and treatment for viral hepatitis. The World Health Organization (WHO) states that viral hepatitis is a bigger threat to Africa than HIV/AIDS, malaria, or tuberculosis with over 1.34 million deaths a year attributed to it.1 Over 60 million people in Africa have hepatitis B which annually accounts for an estimated 68,870 deaths.1 These statistics demonstrate the need for conferences like COLDA to discuss best practices and reduce viral hepatitis in Africa.
Mother-to-Child and Early Childhood Transmission
Hepatitis B is commonly transmitted from mother-to-child and close contact with infected individuals during the first 5 years of life. These modes of infection transmission are preventable with proper birth prophylaxis. There are two types of mother-to-child and early childhood transmission of hepatitis B resulting in chronic infection: vertical and horizontal. Vertical transmission refers to the transmission of hepatitis B from an infected mother to her baby during delivery. Horizontal transmission refers to infection with hepatitis B from direct blood-to-blood contact with an infected individual. Most early childhood transmission cases in sub-Saharan Africa are from horizontal transmission especially during the first 5 years of life from contact with family members or close friends infected with hepatitis B2, though vertical transmission from a hepatitis B infected mother to her baby is also common and completely preventable with birth prophylaxis.
The best way to prevent the transmission of hepatitis B (HBV) from mother to child is through a “birth-dose”, meaning infants are vaccinated against hepatitis B within 24 hours of birth. However, in the WHO Africa region, only 6% of infants are administered the birth-dose.1 Only three countries in Africa: Cameroon, Rwanda, and Mauritania, have national guidelines addressing mother-to-child transmission of hepatitis B.2 Additionally, healthcare providers do not routinely screen future mothers for hepatitis B which contributes to a higher burden.2 This lack of screening demonstrates the need for universal guidelines to provide information to future mothers about hepatitis B. The World Health Organization recently released updated guidelines for hepatitis B which recommends a universal birth dose for all infants, as soon as possible, preferably within 24 hours followed by an additional 2-3 doses (often fulfilled with the pentavalent vaccine). Additionally, the WHO newly recommends that pregnant women testing positive for a hepatitis B infection (HBsAg positive) with an HBV DNA ≥ 5.3 log10 IU/mL (≥ 200,000 IU/mL) receive tenofovir from the 28th week of pregnancy until at least birth, to prevent mother-to-child transmission of HBV.4 This is in addition to the three-dose hepatitis B vaccination in all infants, including the timely birth dose. The WHO also strongly recommends that in settings in which antenatal (pre-birth) HBV DNA testing is not available, HBeAg testing can be used as an alternative to HBV DNA testing to determine eligibility for tenofovir prophylaxis to prevent mother-to-child transmission of HBV.4 Testing for hepatitis B in early pregnancy, a timely birth-dose, pentavalent vaccination, and administration of antivirals in the last trimester if needed would prevent vertical transmission and in turn, prevent horizontal transmission.
HIV/HBV Co-infection
There is a high burden of HIV/HBV co-infection in African countries because both diseases share similar transmission routes such as mother-to-child, unsafe medical and injection practices, and unscreened blood transfusions.2 Chronic HIV/HBV infection is reported in up to 36% of people who are HIV positive, with the highest prevalence reported in west Africa and southern Africa. The co-infection of HIV and HBV is especially dangerous because it accelerates liver disease such as fibrosis and cirrhosis. In fact, liver-related mortality is twice as high among people with an HIV/ HBV co-infection.2
Nosocomial Transmission
Another common way hepatitis B is transmitted in Africa is through nosocomial transmission or transmission from a hospital setting.3 The World Health Organization estimates 24% of blood donations in lower-income countries are not systematically screened for hepatitis B or hepatitis C. Additionally, countries have inconsistent screening procedures and use non-WHO prequalified test kits. Implementation of screening guidelines would significantly assist in reducing the risk of transmitting hepatitis B.
Barriers
There are numerous barriers to eliminating hepatitis B in African countries. Screening is costly and often inaccessible, especially in rural areas. Moreover, there is an irregular supply of test kits for screening for healthcare providers.2,3 Lack of public awareness and often provider knowledge also contributes to the higher hepatitis B burden. Research has found that less than 1% of Gambian adults previously knew their status when tested positive for HBsAg.3 Additionally, there are financial constraints when it comes to hepatitis B treatment and care. The World Hepatitis Alliance and the WHO found that 41% of the world’s population live in countries where there is no public funding for hepatitis B treatments.3 This financial barrier prevents people from accessing important screening and vaccination prevention services. A collaborative effort among governments, local health officials, and community members is needed to manage hepatitis B in African countries.
Importance of Conference
Hepatitis B disproportionately affects the WHO Africa Region where 6.1% of the adult population is infected.1The Conference on Liver Disease in Africa will address problems and discuss potential solutions for this neglected preventable disease. COLDA will help to make eliminating hepatitis B in Africa a reality by engaging the global community to collaborate on public health efforts, develop innovative ideas, and discuss best practices to reduce barriers. We hope to see you there!

August marks the start of National Immunization Awareness Month! This month highlights the importance of vaccines for people of all ages. Let’s talk about why you should get vaccinated for hepatitis B.
Understanding Your Status
Before becoming vaccinated for hepatitis B, it is important to understand your status. You can test through a simple triple panel blood test for HBsAg, HBcAb total and HBsAb. This will tell you if you have a current infection, have recovered from a past infection and if you need to be vaccinated. More details about the blood tests can be found here. Many people with hepatitis B do not look or feel sick so it is important to get tested. Learning your status early can help manage your hepatitis B and identify at-risk close contacts (household/family members or sexual partners) who can then be vaccinated and protected against hepatitis B.
Why You Should Be Vaccinated
The hepatitis B vaccine is the first anti-cancer vaccine because it successfully prevents a hepatitis B infection which is the leading cause of liver cancer worldwide. It’s important for people to receive the vaccine since most people with hepatitis B are not aware they are infected. Hepatitis B is known as a silent infection as many people can live with hepatitis B for years without knowing they are infected. With chronic hepatitis B, when symptoms do finally present, often the infection may have already caused severe liver damage. The hepatitis B vaccine can prevent hepatitis B and also the health consequences that can come from hepatitis B, including the increased risk for cirrhosis, liver failure and liver cancer
It is especially important for future mothers to be tested for hepatitis B and vaccinated if needed. Mothers can easily pass hepatitis B to their infant during childbirth through either vaginal delivery or c-section. The most common mode of transmission of hepatitis B is from mother to child, so administering the vaccine to infants at birth is one of the most effective ways to reduce the number of hepatitis B cases worldwide. Read more about preventing perinatal transmission both in the U.S. and internationally.
In fact, it is very important to vaccinate children, starting with a birth dose, because greater than 90% of acute (short-term infection lasting less than 6 months) cases in infants and up to 50% of infected young children of hepatitis B will progress to chronic (lasting a lifetime) infections while only 5%-10% of adult cases will become chronic. That said, vaccination rates in adults are low and due to the nature of hep B, even those who recover from infection are at risk of reactivation. Left untreated, chronic infections can harm your liver and cause poor health outcomes. That is why the Hepatitis B Foundation calls for universal testing for hepatitis B. Luckily, you can expect to live a long and healthy life when you manage chronic infections of hepatitis B. Learn more about hepatitis B management here.
In the United States, you can get the vaccine through your healthcare provider or health clinics. Ask your doctor if you can get vaccinated today!

About the Hepatitis B Vaccine
Hepatitis B can cause long-term serious damage to the liver like cirrhosis, fibrosis, and liver cancer. Fortunately, a safe and effective vaccine exists which can prevent a hepatitis B infection in all persons.
The World Health Organization recommends the vaccine for infants at birth and children up to age 18. Additionally, the WHO recommends high-risk groups become vaccinated for hepatitis B such as:
Pregnant women
People who frequently require blood to blood products
People who inject drugs
People in prison
Household and sexual contact of people with chronic HBV
Healthcare workers with blood to blood contact
People with multiple sexual partners
Travellers without completion of their vaccine series to endemic areas.
The WHO recommends that infants receive the vaccine within 24 hours of birth followed up with two additional doses. Children up to the age of 18 can also receive this series if they either were not vaccinated for hepatitis B at birth or did not complete the series. The series should be as followed:
1st Dose: Anytime, but for infants, it should be administered at birth
2nd Dose: One month (28 days) after the first dose
3rd Dose: 4 months (16 weeks) after the 1st shot (and at least 2 months after the 2nd shot). Infants should be a minimum of 24 weeks old at the time of the 3rd shot.
You do notneed to restart the hepatitis B vaccine series if you miss any of the shots.
In November 2017, a vaccine was approved by the FDA for use in the U.S. Heplisav-B (Dynavax) is a two-dose vaccine approved for use in adults aged 18 and older. The vaccine is administered as two doses given one month apart.
The Hepatitis B Primary Care Workgroup has released a new resource that helps primary care providers prevent, diagnose, and manage hepatitis B! Hepatitis B experts from diverse health disciplines have contributed to making this comprehensive guide, which is available to download for free on the University of Washington’s website.
Hepatitis B is a complex condition that typically is managed by a liver specialist (hepatologist). However, many people in the U.S. and other parts of the world do not have access to a hepatologist. Many primary care doctors do not feel comfortable or know how to properly care for someone living with hepatitis B. This leaves a large gap in managing and treating the infection. Hepatitis B Management: Guidance for the Primary Care Provider helps to close this gap by giving all providers the tools to understand the virus and how to manage it.
Dr. Amy Tang, Director of Immigrant Health at NorthEast Medical Services and one of the hepatitis B experts involved in creating the guide, answered a few questions about why this resource is so important:
Why was a guide on hepatitis B management needed? What gaps will this help fill?
Primary care providers are recommended to screen and vaccinate for hepatitis B in at-risk individuals. However, when an individual tests positive for hepatitis B, they are typically referred to a specialist for care. Because the majority of persons with chronic hepatitis B in the United States are foreign-born with limited English proficiency and often face both linguistic and access barriers to specialists, referral and retention in specialty care for chronic hepatitis B can often lead to lost follow-up. Chronic hepatitis B management involves visits at least every 6 months for lab monitoring as well as routine ultrasounds for liver cancer surveillance for patients who fulfill high-risk criteria for liver cancer including Asian and African men over 40 years of age and Asian women over 50 years of age. Because primary care is already performing routine blood tests and cancer screening for a variety of other chronic diseases such as diabetes, hypertension, and breast, cervical, and colon cancers respectively, we believe that empowering primary care providers with a simple to use hepatitis B algorithm would promote increased access and retention in care for persons with chronic hepatitis B.
How does this tool work towards the elimination of hepatitis B?
The National Academies of Science, Engineering, and Medicine report for viral hepatitis elimination by 2030 recommends that primary care providers work closely with hepatitis B specialists and their organizations, e.g., the American Association for the StudyofLiver Diseases (AASLD) and theInfectious Disease Societyof America (IDSA), to increase primary care capacity for HBV screening, vaccination, monitoring, and treatment. Thus the National Taskforce on Hepatitis B in collaboration with ECHO Institute and San Francisco Hep B Free—Bay Area hosted a meeting at the 2018 AASLD Annual Liver Meeting in San Francisco to convene a workgroup of hepatitis B specialists in hepatology, infectious disease, public health, primary care, and pharmacy, as well as representatives from American Collegeof Physicians (ACP) and American Academy of Family Physicians (AAFP) to discuss how we can increase primary care capacity for not only hepatitis B screening and vaccination, but also management and treatment.
Currently, the majority of hepatitis B care is managed by specialists. AASLD puts forth guidelines and guidance for hepatitis B every couple of years, however, the guidelines can be lengthy, difficult to access, or intimidating for busy primary care providers to utilize. We polled over 100 primary care providers across the country through the National Association of Community Health Centers’ network of providers and found that primary care providers were interested in managing hepatitis B but felt like they did not have the tools and resources at their fingertips to do it manage it confidently. They reported using web-based references like Up-to-Date for easily accessible guidance on conditions they were less familiar with. Thus, we wanted to create an easy to use document that would be easily accessible and free online. We teamed up with University of Washington’s HepatitisB Online to host our Hepatitis B Guidance for Primary Care Providers as a means to widely disseminate our recommendations and work towards the elimination of hepatitis B in the United States and globally.
How and when should primary care providers use this?
Primary care providers should use this hepatitis B guidance document when they decide to screen a patient for hepatitis B as the document guides them through how to properly screen for hepatitis B in asymptomatic individuals, how to interpret their lab results and provide appropriate counseling, and for patients who screen positive for hepatitis B, how to perform their initial evaluation, monitoring, treatment, and liver cancer surveillance. We also have a dedicated section on perinatal management of women screened for hepatitis B that clearly illustrates the simple steps that can be taken by the primary care provider to prevent transmission of hepatitis B from mother to child.
The guide includes detailed information on the following topics:
Chronic Hepatitis B Testing and Management Algorithm
Interpretation of hepatitis B test results
Tests to run on a hepatitis B surface antigen positive (HBsAg +) individual and how to counsel them
Monitoring and management of the HBsAg + individual
Managing pregnant women who are HBsAg +
Monitoring for liver cancer
The guide is part of Hepatitis B Online – a free suite of materials for providers that supplies information on all topics related to hepatitis B such as when a person should begin treatment and liver cancer screenings. The website also includes prescribing information for approved hepatitis B treatments, and clinical calculators to aid in interpreting predictors of liver damage such as the AST to Platelet Ratio Index (APRI) and fibrosis score.

As a blood-borne virus, it is extremely difficult to track exposure to hepatitis B unless you are aware of somebody’s hepatitis B status. Exposure to the virus can occur at work, through sexual intercourse, unsterile tattoo or drug equipment, or even medical procedures with equipment that was not properly sterilized. Precautions – such as vaccination – should always be taken to avoid a possible infection, but timely actions can also be taken to prevent an infection if an exposure does occur.
Post- Exposure Treatment
If you believe you were exposed to hepatitis B, Post-Exposure Prophylaxis (PEP) is the key to preventing the development of a hepatitis B infection. The first step is to seek medical care as soon as possible and let a healthcare professional know that you may have been exposed to hepatitis B. If you do not have a regular doctor or they cannot fit you in for an appointment, you can also visit a hospital’s emergency department or health care center.
Be sure to be honest with the healthcare professional about how you may have been exposed to hepatitis B, as this will help them to determine your exposure risk and the correct actions to take. PEP is typically given in the form of one dose of the hepatitis B vaccine, but in certain circumstances, the healthcare provider will give one dose of the vaccine in addition to a shot ofhepatitis B immune globulin (HBIG) to provide additional protection. Even if HBIG is unavailable, you should still receive the a dose of the hepatitis B vaccine
Both vaccinated and unvaccinated individuals can receive PEP. However, recommendations for PEP can differ based upon the exposure and whether or not a person has been fully vaccinated. If the source of exposure is known to be hepatitis B surface antigen-positive (HBsAg), the healthcare provider will take the following steps based upon your vaccination status:
Source of exposure is known to be HBsAg positive and individual is unvaccinated – HBIG and hepatitis B vaccine are given as soon as possible within a 24 hour window. Complete full vaccine series as recommended after PEP.
Source of exposure is HBsAg positive and individual is partially vaccinated (less than 3 doses or less than 2 doses of Heplisav-B) – receive HBIG. Complete vaccine series as recommended.
Source of exposure is HBsAg positive and individual has proof of a completed vaccinate series – one dose of hepatitis B vaccine booster is given.
If the source has an unknown hepatitis B status, the recommendations are as follows:
Source has unknown HBsAg and individual is unvaccinated – receive first dose of the hepatitis B vaccine as soon as possible within a 24 hour window.
Source has unknown HBsAg and individual is not fully vaccinated – complete vaccine series.
Source has unknown HBsAg and individual has proof of completed vaccination – no treatment is needed.
The most important part of PEP is the time between the exposure and treatment. PEP is most effective at preventing hepatitis B if it is given as soon as possible after the exposure. This means that the treatment should be given within 24 hours of exposure.
Pregnancy and PEP
PEP is safe and recommended for both pregnant and breastfeeding mothers who have been exposed to hepatitis B; the vaccine will not harm the baby. For pregnant women who are HBsAg positive, PEP must be administered to the newborn to prevent the baby from developing chronic hepatitis B! In this case, the doctor delivering the newborn should be aware of the mother’s hepatitis B infection so that they can have HBIG and the vaccine on hand during the birth. After the baby is born, one dose of HBIG and the first dose of the hepatitis B vaccine should be given to the newborn within 12 hours of delivery. It’s important to note that HBIG may not be available in all countries. In this case, it is even more important to make sure that babies receive the first dose of the hepatitis B vaccine within 24 hours of birth. The newborn should receive the remainder of the vaccine according to the vaccine schedule.
PEP for Healthcare Workers
It’s important to note that occupational procedures have a different set of guidelines, although the timeline and standard PEP treatment recommendations remain the same. Healthcare institutions should always have infection control guidelines and precautions in place to prevent an exposure, but accidents can still occur. All healthcare workers who are exposed to hepatitis B at work should follow the standard protocol for the post exposure process, as explained by the CDC guidelines. The workplace is also responsible for making sure that all employees have access to PEP and all other post-exposure procedure materials as soon as possible after the exposure.
After the 24 Hour Window and No Access to PEP
If you are unable to receive PEP within the recommended time frame, you should still visit a healthcare provider to receive treatment as soon as possible. The CDC estimates that treatment may be effective at preventing infection if given up to 7 days after the initial exposure, but not enough research has been done to confirm how effective PEP is if given after that timeline. The earlier PEP is received, the more likely it is to be effective.
The World Health Organization also recommends that standard first-aid be appliedimmediately to all cuts and wounds that may have been exposed to infected blood. The standard first aid includes 1) letting the wound bleed freely and; 2) washing the wound immediately with soap, gel, or hand-cleaning solution. Be sure to treat the wound gently, and to not use harsh solutions or soaps when cleaning the area. WHO also provides instructions on how properly cleanse eyes, the mouth, and unbroken skin after a potential exposure.
If you believe that you were exposed to hepatitis B and never received PEP, you should be tested to know your hepatitis B status. It takes up to 9 weeks for the hepatitis B virus to show in the bloodstream. Therefore, it is important to get tested for the hepatitis B 3 panel blood test(HBsAg, HBcAb, HBsAb) at least 9 weeks after the exposure to determine if you have been infected. If you remain uninfected after that time period and are HBsAb negative, the completion of the hepatitis B vaccine series is strongly recommended.
