What is Viral Hepatitis?

Hepatitis is the inflammation of the liver tissue that can be caused by infectious agents (i.e., viruses) and non-infectious agents (i.e., drugs or chemical products). While some individuals remain asymptomatic, others may experience symptoms such as jaundice, which is yellowing of the skin and whites of the eyes, along with other signs. Acute hepatitis B and C can last for less than six months but may progress to chronic hepatitis. If left untreated, chronic hepatitis B and C may lead to severe complications, including cirrhosis, liver failure, and liver cancer. It is estimated that 4.4 million Americans are living with chronic hepatitis, but most do not know that they are infected.

- Dark urine or clay-colored stools
