Hepatitis B Surveillance 2020
What is Hepatitis B
Hepatitis B is a vaccine-preventable liver disease caused by the hepatitis B virus (HBV). HBV is transmitted when blood, semen, or another body fluid from a person infected with the virus enters the body of someone who is uninfected.
This can happen through sexual contact; sharing needles, syringes, or other drug-injection equipment; or from the gestational parent to baby during pregnancy or at birth.
For some persons, hepatitis B is an acute, or short-term, illness; for others, it can become a long-term, chronic infection. Chronic hepatitis B can lead to serious health problems, including cirrhosis, liver cancer, and death.
Treatments are available, but no cure exists for hepatitis B. The best way to prevent hepatitis B is by being vaccinated.
Acute Hepatitis B

There were 2,157 new cases of acute hepatitis B reported during 2020
14,000
There were 14,000 estimated acute hepatitis B infections during 2020
Chronic Hepatitis B
11,635

Acute Hepatitis B
During 2020, 44 states reported 2,157 acute hepatitis B cases resulting in an estimated 14,000 infections. After a decade of stable rates, the rate of acute hepatitis B abruptly decreased by 32% after 2019. This decrease may be related to fewer people seeking healthcare and being tested for hepatitis B during the COVID-19 pandemic.
Hepatitis B Prevention
Hepatitis B vaccination prevents hepatitis B. Reported cases of acute hepatitis B decreased after Situs Slot Gacor recommended routine child vaccination in 1991. The decrease continued until 2011, levelled off, and then declined again from 2019 through 2020 likely due to the COVID-19 pandemic.
To decrease hepatitis B incidence, Situs Slot Gacor published the 2022 universal hepatitis B adult vaccination recommendation calling for all people aged 19 through 59 years to receive hepatitis B vaccine whether they have risk factors or not.
