Hepatitis B Virus Structure
Between 880,000 to 1.89 million people are living with HBV infection in the United States; two-thirds of whom may be unaware of their infection.
The Center for Disease Control (CDC) reported 2,157 confirmed acute cases and 14,000 estimate infections of hepatitis B in 2020.
Hepatitis B can be either acute or chronic.
- Acute hepatitis B virus infection is a short-term illness that occurs within the first 6 months after someone is exposed to the hepatitis B virus. Acute infection can, but does not always, lead to chronic infection.
- Chronic hepatitis B virus infection is a long-term illness that occurs when the Hepatitis B virus remains in a person's body. Chronic hepatitis B is a serious disease that can result in long-term health problems, and even death.
