Types of Hepatitis: There are five types of hepatitis virus. This includes Hepatitis A, B, C, D, and E, all of which are considered to be dangerous. According to a report by the World Health Organization, about 1.4 million people are affected by hepatitis A every year.

Hepatitis is also recognized on the basis of severity. In acute hepatitis, there is a sudden inflammation of the liver, the symptoms of which last for six months. With treatment, the disease gradually starts curing. Acute hepatitis is usually caused by HAV infection. The second is chronic hepatitis, in which HIV infection severely affects the patient's immune system. More people are dying due to liver cancer and liver disease.

Hepatitis is caused by blood and infected ingestion: Hepatitis A can be caused by eating contaminated food and consuming contaminated water.
