1. Hepatitis

Viral hepatitis is inflammation of the liver, usually caused by hepatitis virus types A, B, and C. Hepatitis A is a short-term infection, while both B and C can become chronic and lifelong conditions. Contaminated food and water can transmit Hepatitis A, which can live outside the body for months. Hepatitis B is transmitted through infected body fluids, and remains infectious in wet or dry fluids for at least seven days. Hepatitis C is mainly transmitted through direct contact with infected blood and can remain infectious for up to six weeks at room temperature.
