Hepatitis is an inflammation of the liver. Most often, viruses cause hepatitis. There are five main hepatitis viruses: A, B, C, D, and E. Though all cause acute hepatitis, they spread in different ways. Some can turn into chronic hepatitis and lead to cirrhosis, liver cancer, and liver failure.
Viruses A, B, and C are the most common.

Unfortunately, many people with hepatitis don’t have symptoms. According to the Hepatitis Foundation, an estimated 4.4 million Americans are living with hepatitis, and most don’t know they are infected or how they got infected.
With hepatitis C cases on the rise, the U.S. Preventative Services Task Force (USPSTF) recommends hepatitis C screening for high-risk people. Additionally, if you were born between 1945 and 1965, a one-time screening is recommended. Schedule your screenings and vaccinations with your Baylor St. Luke's Medical Group primary care physician.
