People Born Outside of the United States and Viral Hepatitis
People born in any country with a medium-to-high prevalence of hepatitis B (>2%) should be tested for chronic hepatitis B.
Non-U.S.-born people account for 70% of all chronic hepatitis B infections in the United States. CDC recommends hepatitis B testing for:
- People born in any country with medium-to-high prevalence of hepatitis B (>2%). This includes all countries in Asia, the Pacific Islands, and most African countries, especially countries in Sub-Saharan Africa.
- People born in the United States who were not vaccinated at birth and have at least one parent born in a country with high prevalence of hepatitis B (>8%). This includes all countries in East and Southeast Asia (except for Japan), the Pacific Islands, and Sub-Saharan Africa.
Asian Americans, Pacific Islanders, and People Born in Africa at Increased Risk for Hepatitis B
Many countries in Asia, the Pacific Islands, and Africa have high or moderate prevalence of chronic hepatitis B (see map below). The overall prevalence of hepatitis B in the WHO Western Pacific Region is about 6.2%, and nearly 70% of Asian Americans were born outside of the United States. Asian Americans make up 6% of the total population in the United States, but account for 58% of the 862,000 Americans living with chronic hepatitis B. Prevalence is also high among Pacific Islanders living in the United States. The overall prevalence of hepatitis B in the WHO African Region is 6.1%, although certain African countries are experiencing a much higher burden of infection (e.g., Somalia, Zimbabwe, Eritrea, Sudan, Nigeria, and Liberia). During the past 3 decades, migration from an African country of origin to the United States has increased from 200,000 to 1.7 million people. Of people living with chronic hepatitis B in the United States, 12% were born in Africa.
CDC has developed resources, such as fact sheets and community mobilization toolkits, to help educate people born in these countries about the importance of hepatitis B testing.
