Acute hepatitis C infection doesn't always lead to chronic hepatitis C infection. But because a large majority of people with the acute infection go on to chronic infection, acute hepatitis C is serious.
Fortunately, acute hepatitis C can be treated, greatly reducing the risk of chronic infection. Unfortunately, acute hepatitis C usually causes no symptoms, so diagnosis and treatment rarely occur.
Acute hepatitis C develops two weeks to six months after the hepatitis C virus enters your bloodstream. In the small proportion of people who get sick during the acute infection, signs and symptoms include:
- Dark urine
- White-colored stool
- Pain in the upper right part of the abdomen
These signs and symptoms last for two to 12 weeks.
Most acute hepatitis C infections today occur in people who share needles to inject drugs. Health care workers who have needle-stick injuries also are at risk.
If you think you've recently been exposed to the hepatitis C virus, it's important to get tested right away. Blood tests to detect hepatitis C virus proteins, followed by a later test to detect antibodies to the virus, can usually distinguish acute from chronic infection. Having an acute hepatitis C infection makes a difference in the choice of treatment.
