Signs and symptoms
Hepatitis C can affect people differently.
Many people with hepatitis C do not have symptoms and do not know they are infected. If symptoms occur with an acute infection, they can appear any time from 2 weeks to 6 months after exposure.
Symptoms of acute hepatitis C can include:
- Dark urine or clay-colored stools
- Feeling tired
- Fever
- Joint pain
- Loss of appetite
- Nausea, stomach pain, throwing up
- Yellow skin or eyes (jaundice)
Symptoms of chronic hepatitis C can take decades to develop.
Prevention & detection
There is no vaccine to prevent hepatitis C. The best way to protect yourself is to avoid activities that can expose you to the virus — like sharing injection drug use equipment.
