Hepatitis A is commonly known as acute infectious disease of liver caused by HAV (the Hepatitis A Virus), which normally is transmitted bt the fecal-oral (digestive system) route via contaminated food or water. About 10 million people around the world get infected by this disease every year. Thte time of incubation is about two to six weeks and the average incubation period is about 28 days.
This disease occurs more in developing and poor country rather than industrial countries. In Indonesia itself, this disease spreading is quite high because of dirty environment.
Hepatitis A does not have a chronic stage, is not progressive, and does not cause permanent liver damage. Following infection, the immune system makes “antibodies” against HAV (Hepatitis A Virus) that confer immunity against future infection. This disease can be prevented by vaccination and hepatitis A vaccine, that has already been proven effective in controlling outbreaks worldwide.
