NAIRHHA Day 2020

Commemorating National African Immigrant and Refugee HIV & Hepatitis Awareness (NAIRHHA) Day 2020

Each year in September, the Hepatitis B Foundation, along with partners around the U.S., recognizes National African Immigrant and Refugee HIV and Hepatitis Awareness (NAIRHHA) Day. Founded by advocates in Massachusetts, Washington D.C., and New York, NAIRHHA Day has been observed annually on September 9th by healthcare professionals, awareness campaigns, and other organizations since 2014. Although not yet nationally recognized, the Multicultural AIDS Coalition (MAC) and the Coalition Against Hepatitis for People of African Origin (CHIPO) are working to establish NAIRHHA day as its own federally designated awareness day. As explained by Chioma Nnaji, Director at the Multicultural AIDS Coalition’s Africans For Improved Access (AFIA) program, there is a great need to establish NAIRHHA day as its own day. “Several of the current awareness days are inclusive of African immigrant communities, but do not comprehensively address their unique social factors and cultural diversity, as well as divergent histories and experiences in the US.”

Why NAIRHHA Day?

People born outside of the U.S. often face different health challenges than those born in the country and face various barriers to accessing important healthcare services. African immigrants (AI) are disproportionately burdened by HIV and hepatitis B. Advocates for NAIRHHA Day recognized the need to address these health issues in the community and thought that a combined awareness day would be the most effective way to reach the largest number of people impacted.

Hepatitis B presents a significant public health burden for many African countries, and subsequent immigrant populations living in the United States. Although data is limited on hepatitis B infection among African immigrant (AI) and refugee communities in the U.S., studies have shown infection rates are high – between 5 and 18%1,2,3,4,5. One community study in Minnesota even found AIs accounting for 30% of chronic hepatitis B infections 6. AI communities are also known to be disproportionately affected by HIV/AIDS, with diagnosis rates six times higher than the general U.S. population7. Despite this alarming disparity, HIV and hepatitis B awareness, prioritization, and funding has remained limited for this population.

Two of the largest barriers to testing for HIV and hepatitis B among African immigrants are lack of awareness and stigma. Cultural and religious values shape the way people view illness, and there can be fears around testing and diagnosis of illness, and moral implications for why someone may feel they are at risk. While stigma about HIV/AIDS and hepatitis B often come from within one’s own community and culture, it is primarily driven by lack of awareness. Oftentimes, awareness is low in an individual’s home country because of limited hepatitis and HIV/AIDS education, resources, and healthcare infrastructure.  When they arrive in the U.S., awareness remains low for similar reasons. Community health workers and physicians are vital stakeholders to raise community awareness in a culturally sensitive way to help identify current infections and prevent future ones through vaccination.

Commemorating NAIRHHA Day in 2020

Recognizing NAIRHHA Day is important to address the numerous barriers to prevention and treatment that African immigrants face. It was also founded to acknowledge the cultural and ethnic differences that influence how African-born individuals interact with their medical community and the concept of illness. The specific goals of this day of recognition include:

  • Raising awareness about HIV/AIDS and viral hepatitis to eliminate stigma;
  • Learning about ways to protect against HIV, viral hepatitis and other related diseases;
  • Taking control by encouraging screenings and treatment, including viral hepatitis vaccination;
  • Advocating for policies and practices that promote healthy African immigrant communities, families, and individuals.

This year, CHIPO, Multicultural AIDS Coalition, Hepatitis B Foundation and CHIPO-NYC, developed a suite of social media materials to improve awareness and create action around hepatitis B. This year’s campaign is focused on the incorporation of African proverbs into health messaging around ending stigma and increasing hepatitis B and HIV awareness, screening, prevention, and treatment. All graphics and an accompanying list of posts and tweets to go with each one can be found in a Google Drive folder here.  We will be promoting the materials throughout the month of September, and we invite you to share them widely. Together, we can make a difference to address HIV and viral hepatitis among African immigrant communities!

HDV, Hepatitis B Research, Hepatitis Delta (HDV), News

New Hepatitis Delta Treatment Approved by European Commission

New Drug Approved for Treatment of Hepatitis Delta in Europe

A new drug to treat hepatitis delta has now been approved by the European Commission! The drug is called bulevirtide and will be marketed under the brand name Hepcludex. It was previously known at Myrcludex B. This approval follows a quarter century of research and development and is the first drug specifically for hepatitis delta approved in Europe. Due to the high prevalence of the hepatitis delta virus in Russia and the former Soviet Union, it has been approved for use there since the end of 2019, under the name Myrcludex. The European Medicines Agency recommended the drug for approval by the Commission at the end of May 2020 (German Center for Infection Research, 2020).

How Does It Work?

Hepcludex, developed by university researchers in Heidelberg, Germany, works as an entry inhibitor – that is, it prevents hepatitis delta virus (HDV) cells, and the hepatitis B virus (HBV) cells upon which HDV depends, from entering healthy liver cells. Both HDV and HBV cells are able to replicate and thrive exclusively in the liver because they need the bile acid transporter NTCP in order to do so. This transporter is the avenue through which HDV is received into the liver cell. Hepcludex works by blocking this reception process, so that the virus does not continue to infect healthy liver cells (German Center for Infection Research, 2020). The currently infected cells either die or are destroyed by the immune system.

How Have People Responded?

Hepcludex is an injectable medication given daily for 48 weeks. In phase I and II clinical trials, people seemed to respond well to this treatment. It seems that just a small amount of Hepcludex is needed, which is good news because it means that the normal processes of the bile salt transporter (NTCP – the receptor of the hepatitis delta virus) will not be widely disrupted (German Center for Infection Research, 2020). MYR Pharmaceuticals GmbH, which now has the license for Hepcludex, is currently in the process of running further phase II and larger phase III trials, in order to continue to determine long-term effects. Hepcludex has also been tested in combination therapy with PEG Interferon, which is administered weekly also via injection (Highleyman, 2019).

Does it also work for Hep B?

Right now, Hepcludex has been tested and works to treat people with hepatitis delta. Since hepatitis delta becomes the dominant virus in those co-infected with hepatitis B and hepatitis delta, clearing hep delta will not necessarily clear hep B as well. However, the curative properties of this drug for those only affected with hep B are being investigated, both alone and in combination with PEG interferon, and there was a loss of surface antigen (HbsAg) noted in 20% of clinical trial participants who were given this combination (Highleyman, 2019).

What does this mean for patients?

Research thus far indicates that Hepcludex can be more effective than interferon alone, the existing hepatitis delta treatment, which is usually not curative and has challenging side effects (Smith, 2020). Hepcludex is now available for prescription in Europe, although pricing schemes remain unclear. For updated information on pricing and availability, check with your doctor or visit the MYR Pharmaceuticals website here.

Clinical trials will continue to take place for this and other drugs. Researchers and pharmaceutical companies might experience difficulty in recruiting patients for hepatitis delta clinical trials because of a lack of awareness and testing – many people living with hepatitis delta worldwide remain undiagnosed. It is important for people at risk for hepatitis delta to be tested and linked to care if found to be infected. If you have hepatitis delta and are interested in participating in a clinical trial, you can search for one near you. To find a doctor to talk to about getting tested for hepatitis delta if you are living with hep B, click here. Hepatitis delta can often be managed and treated, and you are not alone! The most important first step is to know your status.

What does this mean for providers?

The exact number of people living with hepatitis delta around the world is unknown and estimates range anywhere from 20-70 million. Most of these individuals remain undiagnosed due in large part to a lack of testing and diagnostics. Stephan Urban, one of the researchers leading the effort in the development of Hepcludex has said that, in the United States, fewer than 5% of those tested for hepatitis B are also tested for hepatitis delta (Smith, 2020). It is true that in much of the world diagnostic tools remain unaffordable and so Dr. Urban and his team are developing a much less expensive and rapid test. If the capacity exists, however, testing is crucial for the management of this most severe form of viral hepatitis and all of the subsequent liver conditions that can develop from it. Additionally, as with all infectious diseases, vaccination of ALL people to prevent hepatitis B is critical.

Dental Settings and Hepatitis B

 

Infection Control in Dentistry and its Connection to Hepatitis B

Hepatitis B, a major cause of liver damage and liver cancer, is a silent epidemic worldwide. It is a bloodborne infection that is commonly transmitted through blood and sexual fluids. In the dental office, it is mostly transmitted via blood. It is vital to ensure infection control practices are being followed during dental procedures such as cleanings, extractions, injections, root canals, and surgical procedures to reduce the incidence of hepatitis B.

According to a study from the Department of Periodontology and Endodontics at the State University of New York at Buffalo, unvaccinated dental health care workers have a 10 times greater risk of becoming infected with hepatitis B compared to the average citizen because of possible occupational exposure.[1] The CDC recommends that all health care providers, including those working in dentistry, be vaccinated to protect them. Patients can also play a role by ensuring that they are vaccinated as well. The hepatitis B vaccine is safe and effective and protects for a lifetime!

The transmission of hepatitis B in dental surgery can also be prevented by the routine exercise of good clinical hygiene. The dental clinic must properly and routinely dispose of needles, sterilize instruments, and comply with all standard precautions (e.g., wearing appropriate personal protective equipment and disinfecting all equipment and surfaces after each patient) for all patients. In the 2016 update of Transmission of blood-borne pathogens in US dental health care settings, the authors identified lapses in infection prevention practices and failure to adhere to Centers for Disease Control and Prevention (CDC) recommendations as the major causes behind breakouts of hepatitis B in dental settings (see CDC guidelines for the United States here).[2] Examples of lapses included the failure to heat-sterilize handpieces between patients, a lack of training for interns/personnel, and the use of a combination of unsafe injection practices. [2] These reports emphasize the need to improve dental health care personnel’s understanding of the basic principles of infection control.

While at your dentist’s office, you can play a role in ensuring the staff implements proper infection control practices. Before being seated, make sure the chair and all surfaces have been properly wiped down after the previous patient completed treatment. Ensure there is no visible blood or saliva on any surfaces. Before any work is done, ask your dentist if the instruments have been properly disinfected or sterilized. Then, your dentist should take a thorough medical history, asking specific questions about medications, current illnesses, recurrent illnesses, or other infections. Your dentist should also use new protective attire and barrier techniques such as gloves, surgical masks, protective eyewear, and a gown or laboratory coat. In addition, do not be afraid to seek affirmation that the dentist has washed their hands prior to your treatment. When using sharp instruments or needles your dentist should use extraordinary care to prevent unintentional injuries. The needle should be properly disposed of or recapped to decrease the risk of needlestick injury.

The lack of awareness about the importance and dangers of hepatitis B often stems from dental schools. The Himachal Institute of Dental Sciences in Paonta Sahib, India conducted a study which revealed that while dentists are among the high-risk transmission groups for hepatitis, they have little knowledge or information on hepatitis B and/or the vaccine.[3] The study also concluded that proper infection control, sterilization, and prophylactic vaccination protocols should be followed in order to reduce the risk of hepatitis in India.[3] Another study, performed by Saveetha Dental College & Hospital in Chennai, India, evaluated the awareness of the hepatitis B virus among dental graduate students at the University Dental College.[4] A questionnaire regarding the awareness of hepatitis infections and various infection control measures was distributed among all the students in the dental graduate program.4 The data extracted showed that final year students had an increased awareness when compared to third-year students.[4] The overall awareness among the students was unsatisfactory and further signifies the need for continued infection control education.

Similarly, a study performed at Obafemi Awolowo University in Nigeria evaluated the attitude of 120 students towards the hepatitis B vaccine through an anonymous questionnaire.[5] The results showed that of the 94.7% of the students who did not receive the vaccine cited their busy schedule as the reason for their failure to be vaccinated.5 Furthermore, the University of Pretoria in South Africa conducted a study aimed to determine the knowledge among 292 dental students on the transmission and prevention of the hepatitis B virus.[6] It was found that more than 50% of the students did not know that the hepatitis B infection can be transmitted through piercings and more than 50% of the nonclinical students wrongly reported that antibiotics can be used to prevent infection after exposure.6 These studies demonstrate that there is a lack of knowledge surrounding hepatitis B in some dental school settings which contributes to insufficient knowledge about hepatitis B in professional dental settings.

Although awareness about hepatitis B is improving worldwide, dental schools must begin to stress its prominence and importance of infection control in dental settings. It is a good idea for patients to ask about the infection control practices implemented at their dental offices. Emphasis should always be placed on consistent adherence to recommended infection control strategies, and each dental clinic should have a written protocol for instrument reprocessing, operatory cleanup, and management of injuries. Such efforts will lead to the development of safer and more effective medical devices, work practices, and personal protective equipment; all in conjunction decreasing the incidence of hepatitis B.

Be the Voice Story Bank Launch

 

 

What is B the Voice Story Bank

The Hepatitis B Foundation today announced the launch of its B the Voice Story Bank. Building upon the success of our national #justB campaign – launched in partnership with StoryCenter and AAPCHO in May 2017 – we are excited to expand our storytelling efforts internationally. Almost 300 million people worldwide live with chronic hepatitis B, but so many of their stories remain untold. Often this is due to stigma, fear of discrimination, lack of community awareness or understanding of the disease, or lack of support for those wishing to speak out publicly about hepatitis B. The new B the Voice Story Bank provides an online platform for people living with hepatitis B, their families, and community health workers and health care providers to share their first-hand knowledge and experiences with a global audience.

Documenting and sharing the impact that hepatitis B has on individuals, families, and communities around the world is essential in keeping up the momentum to find a cure for hepatitis B and to achieve the global elimination targets set by WHO to be achieved by 2030.

Why is B The Voice Story Bank Important?

“This new program provides many more people with the chance to tell their stories about living with hepatitis B around the world, and the Foundation and our partners will continue sharing this compelling content through our social media and other means” – Chari Cohen, DrPH, MPH (Senior Vice President, Hepatitis B Foundation)

“Speaking out relieves one from self-stigma and denial, but more importantly creates room for one to advocate towards changing something for the better. When you keep silent, the people in power will assume everything is okay until one comes out to challenge the status quo… I also want people to know that while Hepatitis B is a silent killer, one can live a positive and productive life as long as one knows early and follows the doctors’ advice.” -Kenneth Kabagambe, Director, Africa Hepatitis Initiative (Kampala, Uganda)

“Centering the voices of people living with hepatitis B is critical in raising awareness, combating stigma and discrimination, and encouraging more people to speak out or take action in other ways.” “That’s true whether it means getting tested for hepatitis B, talking to a doctor, educating family or community members about prevention or advocating for resources and policies to support countrywide hepatitis B elimination.” – Rhea Racho, MPAff (Public Policy and Program Manager, Hepatitis B Foundation)

Addressing Hepatitis B in Africa

Conference on Liver Disease in Africa

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.1 The 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!

Get Vaccinated for Hepatitis B!

 

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!

Hepatitis B is a preventable virus so why not take steps to become a healthier you!

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.

Find out more about the vaccine schedule here!

You do not need 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.

Ask your doctor about the 2-dose vaccine. You can now find Heplisav-B at more than 1,700 Albertsons Companies’ store pharmacies across the US. For assistance accessing this vaccine, you can contact Heplisav-B’s Access Navigator at 1-844-375-4728.

#ThrowbackWHD: Hep B United Summits, Advocacy Days and World Hepatitis Days Through The Years

 

While we were not able to gather together for our annual Hep B United Summit this World Hepatitis Day to discuss best practices, advocate on Capitol Hill, and innovate ideas together to improve testing,  hep B vaccination and linkage to care and treatment for hep B in our communities, we did have our Virtual Week of Advocacy. Hep B advocates emailed their Congress members to ensure policy priorities include provisions for hepatitis B elimination -specifically supporting funding for a hep B cure and CDC viral hepatitis programs.  You too can advocate for hepatitis B elimination here! The templates make it so easy!

To learn more about past  Hep B United Summits, check out previous summit agendas and presentations here.

Join us today, World Hepatitis Day, for a Twitter Storm all day long sharing  memories, pics and videos  from past Hep B United Summits,  Advocacy Days and  World Hepatitis Day events.  Tag your posts and pics with #ThrowbackWHD, #WorldHepatitisDay, and #HepBUnite. Be sure to tag @HepBUnited and @HepBFoundation on Instagram, Twitter, or Facebook!

292 Million People Worldwide Have Hepatitis B – So Why Do We Feel Alone?

 

Hepatitis B is the global pandemic no one talks about, yet 292 million people worldwide have been infected. In 2015, the World Health Organization estimated that hepatitis B caused 887,000 deaths annually.

Today, 292 million people have chronic hepatitis B1. Despite the availability of an effective vaccine, the number of people living with hepatitis B virus is projected to remain at the current, unacceptably high level for decades and cause 20 million deaths through 2030.

How can this happen? Viral hepatitis infection and death rates far outstrip that of ebola and zika. In fact, you have to combine the death toll from HIV and tuberculosis to find human suffering on par with what viral hepatitis causes around the world each year. How has this pandemic remained so hidden and ignored for so long? There are several factors that have kept hepatitis B off public health’s global radar. It’s a complicated, silent infection, often with few or no symptoms. Those who have it have been silenced by shame and ignorance, and more than two-thirds of those infected with hepatitis B have never been tested and are unaware of their positive status.

And then there’s avoidance by the global healthcare community. The development of a hepatitis B vaccine 40 years ago was thought to signal the death knell of this disease. While new infections have plummeted in North America and Europe, in impoverished countries, the vaccine is often not available or too expensive and infected mothers continue to unknowingly infect their children at birth.

There have been successful hepatitis B immunization campaigns around the world, even in poor, remote areas, but there’s a catch. The Global Vaccine Alliance (Gavi) provides a free hepatitis B pentavalent vaccine which is effective in children starting at 6 weeks of age. To break the mother-to-child infection cycle, a different and more costly hepatitis B vaccine must be administered as-soon-as-possible, within 12 hours of birth. However, this vaccine is often unavailable and out-of-reach financially in rural Africa and Asia, which is why chronic hepatitis B rates remain stubbornly high and are projected to remain unchanged.

To successfully combat hepatitis B, communities need to launch campaigns that combat stigma and teach how to prevent the spread of the disease through education and immunization. They need the resources to test people for hepatitis B and vaccinate those who need it. They also need to teach healthcare providers how to treat patients with liver damage.

Fortunately, we have started to see change. On May 28, 2016, at the United Nations World Health Assembly, 194 countries made a historic commitment to eliminate viral hepatitis by 2030. The Global Health Sector Strategy for Viral Hepatitis pledges to reduce deaths from hepatitis B and C by 65 percent and increase treatment by 80 percent. This action is the greatest global commitment to viral hepatitis ever taken.

On July 28, 2016, a campaign called NOhep, the first global movement to eliminate viral hepatitis, launched on World Hepatitis Day by the World Hepatitis Alliance. This day was chosen to mark the birthday of Baruch S. Blumberg, MD, D.Phil, who won the Nobel Prize in Medicine for the discovery of the hepatitis B virus.

Many of our partners and other organizations around the world are raising awareness to highlight World Hepatitis Day. Here are some of the activities you can support.

About Hepatitis B, HBV, HDV, Hepatitis B Awareness, Hepatitis Delta (HDV)

Know Your ABCs

What is Hepatitis?

Hepatitis simply means inflammation of the liver which can be caused by infectious diseases, toxins (drugs and alcohol), and autoimmune diseases. The most common forms of viral hepatitis are A, B, C, D, and E. With 5 different types of hepatitis, it can be confusing to know the differences among them all.

The Differences

While all 5 hepatitis viruses can cause liver damage, they vary in modes of transmission, type of infection, prevention, and treatment.

Hepatitis A (HAV) is highly contagious and spread through fecal-oral transmission or consuming contaminated food or water1. This means that if someone is infected with hepatitis A they can transmit it through preparing and serving food and using the same utensils without first thoroughly washing their hands. Symptoms of HAV include jaundice (yellowing of skin and eyes), loss of appetite, nausea, fever, abnormally colored stool and urine, fever, joint pain, and fatigue1. Sometimes these symptoms do not present themselves in an infected person which can be harmful because they can unknowingly spread the virus to other people. Most people who get HAV will feel sick for a short period of time and will recover without any lasting liver damage2. A lot of hepatitis A cases are mild, but in some instances, hepatitis A can cause severe liver damage. Hepatitis A is vaccine preventable and the vaccine is recommended for people living with hepatitis B and C. Read this blog post for a detailed comparison of hepatitis B and hepatitis A!

Hepatitis B (HBV) is transmitted through bodily fluids like blood and semen, by unsterile needles and medical/dental equipment and procedures, or from mother-to-child during delivery1. HBV is considered a “silent epidemic” because most people do not present with symptoms when first infected. This can be harmful to individuals because HBV can cause severe liver damage, including cirrhosis and liver cancer if not properly managed over time3. Hepatitis B can either be an acute or chronic infection meaning some cases last about 6 months while other cases last for a lifetime. In some instances, mostly among people who are infected as babies and young children, acute HBV cases can progress to a chronic infection3. Greater than 90% of babies and up to 50% of young children will develop lifelong infection with hepatitis B if they are infected at a young age.

Hepatitis C (HCV) is similarly transmitted like HBV through bodily fluids, like blood and semen, and by unsterile needles and medical/dental equipment and procedures. Symptoms of HCV are generally similar to HAV’s symptoms of fever, fatigue, jaundice, and abnormal coloring of stool and urine1, though symptoms of HCV usually do not appear until an infected individual has advanced liver disease. Acute infections of hepatitis C can lead to chronic infections which can lead to health complications like cirrhosis and liver cancer1. Read this blog for a detailed comparison of hepatitis B and hepatitis C!

Hepatitis Delta (HDV) infections only occur in persons who are also infected with hepatitis B1,3. Hepatitis Delta is spread through the transfer of bodily fluids from an infected person to a non-infected person. Similar to some other hepatitis viruses, hepatitis Delta can start as an acute infection that can progress to a chronic one. HDV is dependent on the hepatitis B virus to reproduce3. This coinfection is more dangerous than a single infection because it causes rapid damage to the liver which can result in fatal liver failure. Find out more about hepatitis B and hepatitis Delta coinfection here!

Hepatitis E (HEV) is similar to hepatitis A as it is spread by fecal-oral transmission and consumption of contaminated food and water1. It can be transmitted in undercooked pork, game meat and shellfish. HEV is common in developing countries where people don’t always have access to clean water. Symptoms of hepatitis E include fatigue, loss of appetite, stomach pain, jaundice, and nausea. Talk to your doctor if you are a pregnant woman with symptoms as a more severe HEV infection can occur. Many individuals do not show symptoms of hepatitis E infection1. Additionally, most individuals recover from HEV, and it rarely progresses to chronic infection. Read this blog for a detailed comparison of hepatitis B and hepatitis E!

Here is a simple table to further help you understand the differences among hepatitis A, B, C, D, and E.

Prevention

Fortunately, hepatitis viruses are preventable.

Hepatitis A is preventable through a safe and effective vaccine. The Centers for Disease Control and Prevention (CDC) recommend that children be vaccinated for HAV at 12-23 months or at 2-18 years of age for those who have not previously been vaccinated. The vaccine is given as two doses over a 6-month span1. This vaccine is recommended for all people living with hepatitis B & C infections

Hepatitis B is also preventable through a safe and effective vaccine. The vaccine includes 3 doses over a period of 6 months, and in the U.S. there is a 2-dose vaccine that can be completed in 1-month1,3. Read more here, if you would like to know more about the vaccine series schedule.

Hepatitis C does not have a vaccine, however, the best way to prevent HCV is by avoiding risky behaviors like injecting drugs and promoting harm reduction practices. While there is no vaccine, curative treatments are available for HCV1.

Hepatitis Delta does not have a vaccine, but you can prevent it through vaccination for hepatitis B1,3.

Hepatitis E does not have a vaccine available in the United States. However, there has been a vaccine developed and licensed in China1,2.

Are You At Risk For Hepatitis B

 

An estimated 292 million people worldwide are living with chronic hepatitis B and most are unaware of their status. Many at-risk groups are Asian and African descended. This month, we join our global community to observe World Hepatitis Day on July 28th – a day chosen to commemorate the birthday of Dr. Baruch Blumberg, who won the Nobel Prize for the discovery of the hepatitis B virus  Let’s take action and raise awareness to find the “missing millions”!

Not knowing your hepatitis B status can cause long term damage to your liver, so it is important for you to understand risk factors besides ethnicity. The CDC’s Know Hepatitis B Campaign’s fact sheet, “Hepatitis B – Are You At Risk?” is a great resource for sharing basic information on getting tested for hepatitis B. The fact sheet is available in 14 languages including Burmese, Khmer, French, Somali, Amharic, Hmong, and Swahili, among many others!

 For more information about the Know Hepatitis B Campaign, which is co-branded with Hep B United, visit the campaign website.

So if you think you are at risk –  what are the next steps? The first thing you can do is visit your healthcare provider to see if you should be tested for hepatitis B. 

A simple blood test can check to see if you are infected or at risk for hepatitis B. The hepatitis B panel blood test includes the following tests: 

  1. HBsAg (Hepatitis B surface antigen) – A “positive” or “reactive” HBsAg test result means that the person is infected with hepatitis B. If a person tests “positive,” then further testing is needed to determine if this is a new “acute” infection or a “chronic” hepatitis B infection. A positive HBsAg test result means that you are infected and can spread the hepatitis B virus to others through your blood.
  2. anti-HBs or HBsAb (Hepatitis B surface antibody) – A “positive” or “reactive” anti-HBs (or HBsAb) test result indicates that a person is protected against the hepatitis B virus. This protection can be the result of receiving the hepatitis B vaccine or successfully recovering from a past hepatitis B infection. A positive anti-HBs (or HBsAb) test result means you are “immune” and protected against the hepatitis B virus and cannot be infected. You are not infected and cannot spread hepatitis B to others.
  3. anti-HBc or HBcAb (Hepatitis B core antibody) – A “positive” or “reactive” anti-HBc (or HBcAb) test result indicates a past or current hepatitis B infection. The core antibody does not provide any protection against the hepatitis B virus (unlike the surface antibody described above). This test can only be fully understood by knowing the results of the first two tests (HBsAg and anti-HBs). A positive anti-HBc (or HBcAb) test result requires talking to your health care provider for a complete explanation of your hepatitis B status.

You can see what each test result means in this table!

Ask your doctor if you should be tested today!
