Hepatitis A disease is caused by Hepatitis A virus (HAV).

The main route of transmission is faecal oral route, occasionally HAV is transmitted by blood products or through illicit use of injectable drugs.

Faecal oral route means if anyone have hepatitis disease and after going toilet he does not clean his hand properly and touch some food or water than that material is infected by this virus.

If somebody drink that water or eat that infected food than he/she will also suffer from this disease within 2 to 6 weeks.

This type of problem occurs mostly in areas of overcrowding and poor sanitation.


Hepatits is that kind of disease in which some have symptoms & some may not have any symptoms. Many cases have few or mo symptoms, especially in young. 

The risk of symptomatic infection is directly related with age. Mostly children having either asymptomatic or unrecognized infections. More than 80% of adults having mild symptoms. Acute liver failure may rarely occur, it is more common in old age.

Symptoms usually last less than 2 months, although it may be lasts for upto 6 months.If symptoms arises, that are as mention below.
