Hepatitis C

  • Hepatitis C is a virus (HCV) that can cause inflammation of the liver.
  • It is mainly spread from the blood from an infected person, for example, while sharing needles, or other equipment that has been exposed to blood, to inject drugs, or through needle-stick injuries.
  • For most people (70%-85%), hepatitis C is a long-term chronic condition that can result in long-term serious health problems and even death.
  • Most infected people may not be aware of their infection if they are not ill with symptoms.
  • There is no vaccine for hepatitis C.
  • The best way to prevent hepatitis C is to avoid behaviors that can spread the disease, such as injecting drugs, and decrease the risk of occupational exposure (for healthcare workers) by adhering to Standard Precautions.
