Hepatitis B is a global public health crisis. While it is heavily underreported across the world, experts estimate that there are approximately 300 million people living with chronic hepatitis B. Anyone can get hepatitis B. The hepatitis B virus does not discriminate. This is why it is crucial for everyone to get tested for hepatitis B at least once in their lifetime and get the hepatitis B vaccine.
However, some people are at a greater risk for developing chronic hepatitis B than others. This is not necessarily because some people are genetically predisposed to the virus but because of poor awareness and lack of resources to prevent or treat hepatitis B. It is important to understand that health is influenced by many different factors including genetics, our environment, availability of resources and access to care. To fully understand the reasons behind racial and ethnic disparities in hepatitis B prevalence across the globe, we must understand the social determinants of health associated with hepatitis B testing and care.
Differences in HBV Genotypes
Genotypes describe the characteristics of the virus. The hepatitis B virus (HBV) contains many different genotypes, which explains why the virus impacts people in different ways (i.e., how the virus spreads to others, likelihood of developing serious liver disease, etc.). Some genotypes such as genotype A can increase the chances of chronic (long-term) infection.
Certain HBV genotypes are more common in some regions of the world than others, which may explain why some people are more likely to experience worse health outcomes than others (Sunbul, 2014).
Genotype A is commonly found in the African region. Genotypes B and C are found in the Asia Pacific regions. Genotype D is less likely to lead to a chronic infection but can still result in serious liver failure without proper intervention. Genotype D is found mostly in South Asia (Pakistan and India).

Social Determinants of Health
Public health researchers call the economic, cultural and political factors that shape society “social determinants of health,” which go beyond medical care and insurance coverage. Our health is influenced by our access to education, employment opportunities, local, state and national policies, and our neighborhood and environment. (Greene at al., 2017).
In the global context of hepatitis B prevention and treatment, some groups are at a better advantage than others. Some countries are more technologically advanced with a strong economy. This makes access to testing, vaccine, clinical trials, and treatment options much easier for some populations (though disparities still exist). Political will and access to economic resources impact what public health issues should be prioritized for in many countries. If a country has a poorly maintained economy and access to resources is limited, it is less likely to develop or sustain critical public health programs to prevent or test for hepatitis B or provide proper care for those living with hepatitis B. In some regions, access to schools and education is restricted, which impacts health literacy and access to economic mobility. Poor awareness due to low health literacy and limited knowledge about hepatitis B is usually because of overall education deficiencies. This makes it difficult for people to understand health education if they lack basic literacy skills (i.e., if they cannot read or write). In other regions, health literacy is not prioritized. Some people have better access to tools and resources that help them understand how to navigate the health care system, get medical insurance and make better decisions about their health (e.g., starting treatment or routinely getting ultrasounds to monitor liver function) (Greene et al., 2017).
In the U. S., hepatitis B is an important health concern for many Asian and African immigrant populations. This is partially due to low or poor vaccination rates in their country of origin (some countries do not have policies on mandatory vaccination, access to adult vaccination or sufficient access to birth dose). While people should be getting screened for hepatitis B during the immigration process, this does not always occur. Immigrant populations also tend to have lower rates of insurance coverage. Many either lack healthcare insurance or do not have adequate insurance.
Cultural barriers pose a critical challenge to getting people screened and vaccinated as health education materials on hepatitis B are not always available in other languages, such as Khmer or Mandarin. This makes them more likely to avoid getting care or using preventative services such as hepatitis B screening and vaccination due to fears of high out-of- pocket costs, disruptions in their immigration process and cultural factors. Cultural barriers pose a critical challenge to getting people screened and vaccinated as health education materials on hepatitis B are not always available in their native languages.
The Hepatitis B Foundation and the Hep B United Coalition work with local, national, and global partners to address barriers around hepatitis B and liver cancer for impacted communities. Local coalitions such as Hep B United Philadelphia work with community-based organizations like African Family Health Organization (AFAHO), Philadelphia Chinatown Development Corporation (PCDC), and SHAMS Health Clinic to increase uptake of screening and provide education on hepatitis B and liver cancer among Asian and African immigrant communities.

Amina asked her doctor how she could get rid of this virus. Her doctor explained to her that there is no cure for hepatitis B, but antiviral treatment options do exist. While she may not be able to completely get rid of the virus, she can help protect herself from serious conditions such as hep B related cirrhosis or liver cancer with treatment. Amina’s doctor encouraged her to get treatment to prevent any serious problems from occurring. He also mentioned that treatment for hepatitis B is safe and effective. This did not make any sense to Amina. She thought to herself that if a treatment wouldn’t cure her of the disease, then there is no point in taking it. She felt healthy and did not show any symptoms. After the doctor suggested treatment options, she said that she will wait for the cure.
After moving to the U.S., Amina had gotten busy with school and work and did not follow up with her primary care doctor for years. Amina experienced stomach pains from time to time but they often went away on their own. On one occasion, her stomach pain worsened. She had to take a few days off from work to get better using home remedies, but they didn’t help. Finally, she went to the doctor’s office to learn more. She discovered that she had liver cancer. Her doctor referred her to a hepatologist (a liver specialist) for further treatment.
The hepatologist explained to Amina that hepatitis B can lead to liver cancer without monitoring and treatment. Even though a cure is not available, treatment options do exist, and they help in slowing and preventing serious liver disease, liver damage or liver cancer. If Amina had started antiviral treatment on time, she could have saved her liver. The doctor recommended chemotherapy for Amina to treat the cancer. Not only did her medical bills go up but Amina felt physically and mentally exhausted by the procedures. She advocates for everyone living with hepatitis B to get treatment if they need it and not wait for the cure. She also participates in advocacy efforts to make treatment options more affordable for people living with hepatitis B.



Yufei Zhao is 45 years old and lives with his family in Philadelphia, Pa. Yufei discovered that he had hepatitis B when he attended a community health fair with his family. Even though he was instructed to talk about his diagnosis with a doctor and learn more about possible treatment options, Yufei decided to do nothing as he did not feel sick. While he has health insurance through his employer, he never utilizes any health care services. He often skips annual wellness visits as he says he “never gets sick.”
A few weeks ago, Yufei’s family noticed that he has been skipping meals frequently saying he’s full or not hungry. At his daughter’s urging, he decided to go for a visit. After conducting some more tests, his doctor explained that the chronic infection with the hepatitis B virus had progressed substantially, and he had developed cirrhosis. After an MRI diagnosis, it was revealed that Yufei had liver cancer
The Hepatologist (liver doctor) explained to Yufei that the liver is an important organ and acts as a cleaning system for the body. It removes toxic waste, purifies blood, and helps to digest food properly. When the virus entered the liver, it made many copies of itself and started attacking healthy liver cells. This led to inflammation and weakened the ability of the liver to carry out its most essential tasks. Because he was never monitored for hepatitis B, the virus allowed tumors to grow in the liver which caused the cancer. When the tumors grow in size or number, it eventually spreads to other parts of the body and disrupts other vital processes as well.
The doctor mentioned that liver cancer is often called the silent disease because symptoms may not always be present. Even with a hepatitis B, a person could look or feel okay but that does not mean the virus isn’t active and causing damage. When the symptoms do show up, it might be too late to prevent liver cancer. After discussing his options with the doctor, Yufei learned that the best treatment for him was to get a liver transplant.
