Hepatitis C
The Hepatitis C virus causes chronic infection in 50–80% of infected persons (or 5 to 8 out of every 10). About 40-80% of these cases (or 4 to 8 out of 10) clear up with treatment. Although this almost never happens, chronic Hepatitis C can sometimes clear up on its own, without treatment. Doctors suggest that people with chronic Hepatitis C should avoid drinking alcohol and taking medications that can be toxic (or poisonous) to the liver. They also suggest that people with chronic infections should be given vaccines for Hepatitis A and Hepatitis B. People with cirrhosis should also have ultrasound tests for liver cancer.
