Hepatitis B (acute and chronic)
Hepatitis B is a contagious liver disease that results from infection with the hepatitis B virus. It can be either acute or chronic. Acute hepatitis B virus infection is a short-term illness that occurs within the first six months after someone is exposed to the virus. Chronic hepatitis B virus infection is a long-term illness that occurs when the 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.
A total of 15 cases, or 0.5 cases for every 100,000 persons, of acute hepatitis B were reported to CADE in 2011. Eighty-seven percent of the cases were males. Nationally, acute hepatitis B infections occur 1.8 times more often in men than in women.
The Centers for Disease Control and Prevention (CDC) estimates there were 43,000 new hepatitis B infections in the U.S. in 2007. CDC estimates that there are between 800,000 and 1.4 million people living with chronic hepatitis B disease in the US.
There were 182 confirmed or probable chronic hepatitis B cases reported in 2011 in Iowa.
