Hepatitis C virus has not been shown to be transmitted by mosquitoes or other insects.

No, if you ever tested positive for the Hepatitis C virus (or Hepatitis B virus), experts recommend never donating blood, organs, or semen because this can spread the infection to the recipient.

Yes, even if a person with Hepatitis C has no symptoms, he or she can still spread the virus to others.

Yes. It is common for persons with chronic Hepatitis C to have a liver enzyme level that goes up and down, with periodic returns to normal or near normal. Some infected persons have liver enzyme levels that are normal for over a year even though they have chronic liver disease. If the liver enzyme level is normal, persons should have their enzyme level re-checked several times over a 6–12 month period. If the liver enzyme level remains normal, the doctor may check it less frequently, such as once a year.

There is no evidence that people can get Hepatitis C from food handlers, teachers, or other service providers without blood-to-blood contact.

The Hepatitis C virus can survive outside the body at room temperature, on environmental surfaces, for at least 16 hours but no longer than 4 days.
