Hepatitis C is an infection of the liver. It's caused by the hepatitis C virus. About 3.2 million people in the U.S. have the disease, but because the virus causes so few symptoms, most of them don't know they have it.
There are many types of hepatitis C virus. The most common in the U.S. is type 1. No type is more serious than any other, but they respond differently to treatment.
Because hepatitis C doesn't always cause symptoms, you may not know you have the virus. Your doctor won't check for hepatitis C unless you think you've had contact with a person who is infected or if you were born between 1945 and 1965. If you think you may have hepatitis C, you can get a blood test.
The CDC recommends that you have a bloodtest for hepatitis C if any of the following are true:
You received blood from a donor who later was found to have the disease.
You have ever injected...
You can get a blood test to see if you have the hepatitis C virus.
Are There Any Long-Term Effects of Hepatitis C?
Yes. In people who have hepatitis C, 75% to 85% may develop a long-term infection. Hepatitis C is one of the top reasons that people need a liver transplant.
What's the Treatment for Hepatitis C?
Hepatitis C treatments have changed a lot in recent years. The latest is a once-daily pill called Harvoni that cures the disease in most people in 8-12 weeks. It combines two drugs: Sovaldi (sofosbuvir) and ledipasvir. In clinical trials, the most common side effects were fatigue and headache.
