How do you know if hepatitis B is acute or chronic?
If you test positive for HBsAg for longer than six months, it means you have a chronic hepatitis B infection. But, if you no longer test positive (or “reactive”) for HBsAg after six months and you develop hepatitis B surface antibodies (HBsAb), then you have cleared hepatitis B after an “acute” infection.
Is hepatitis B considered chronic?
For some people, hepatitis B infection becomes chronic, meaning it lasts more than six months. Having chronic hepatitis B increases your risk of developing liver failure, liver cancer or cirrhosis — a condition that permanently scars of the liver.
Which hepatitis is acute and chronic?
If you have the hepatitis C virus in your blood for anywhere from a few weeks to a few months, you have “acute” hep C. After 6 months, it's called “chronic.” Without diagnosis and treatment, chronic hep C can remain for many years and lead to serious symptoms like liver damage.
Which hepatitis is chronic?
Long-term infection with the hepatitis C virus is known as chronic hepatitis C. Chronic hepatitis C is usually a "silent" infection for many years, until the virus damages the liver enough to cause the signs and symptoms of liver disease.
Does acute hepatitis B go away?
The acute illness most often goes away after 2 to 3 weeks. The liver most often returns to normal within 4 to 6 months in most people. Almost all newborns and about one half of children who get hepatitis B develop the chronic condition. Very few adults who get the virus develop chronic hepatitis B.

Hepatitis B is a disease caused by the hepatitis B virus (HBV) that can be self-limited for some and lifelong for others. HBV is transmitted through the blood or bodily fluids of an infected person.
Cases and Clusters of Potential Public Health Importance
Jurisdictions should review and analyze hepatitis B data regularly to identify cases and clusters of hepatitis B that merit further investigation. When resources are limited, these should be prioritized for investigation based on the degree of public health importance. The following are examples of high priority cases and clusters:
Interpretation of Laboratory Test Results
A description of hepatitis B laboratory markers can be found in Appendix B.
Recommended Reportable Laboratory Markers
The following laboratory markers are recommended for reporting to public health, as they can aid in case ascertainment, case classification, and monitoring care continua for hepatitis B:
Case Reporting and National Notification
Cases of acute, chronic, and perinatal hepatitis B, and hepatitis B during pregnancy should be reported to HDs as specified by state, territorial, or local regulations. Acute, chronic, and perinatal hepatitis B are nationally notifiable conditions ( 5 ).
Surveillance of Acute and Chronic Hepatitis B
The national incidence of acute hepatitis B dramatically declined after incremental recommendations for vaccinating people at-risk for infection and severe outcomes were released beginning in 1982 ( 47) and for infants and children in 1991 ( 53 ).
Surveillance of Hepatitis B During Pregnancy and Perinatal Hepatitis B
Knowledge of a pregnant person’s HBV infection status is essential for preventing perinatal hepatitis B.

In some cases, symptoms may not even show up at the start, and the infected individual may be able to get relief from the virus without any complications. However, for some adults, the infection is not fully treated even with long-term medications, causing a more severe form of the infection, also known as chronic hepatitis B.
