Hepatitis A
Posted by: admin : Category: Hepatitis A
Hepatitis A (formerly known as infectious hepatitis) is an acute infectious disease of the liver caused by the hepatovirus hepatitis A virus. Most commonly transmitted by the fecal-oral route, such as contaminated food, hepatitis A does not typically have a chronic stage and does not cause permanent liver damage. The patient’s immune system makes antibodies against the hepatitis A virus that confer immunity against future infection. Some vaccines remain effective for a lifetime, while others have to be updated after a few months or years.
