Hepatitis C is a virus that attacks your liver. You can live with hepatitis C for 20 to 30 years or more without feeling sick even though the virus is injuring the liver, making it hard for it to work properly. The liver is a very important organ in your body that you cannot live without.
Hepatitis C is spread when the blood of a person with hepatitis C comes in contact with the bloodstream of someone else. This can happen through breaks in the skin or in the lining of the nose and mouth. Hepatitis C is a strong virus and can survive outside of the body for many days. This means dried blood can also pass the virus.
