Is there any way to determine how old is hepatitis C virus infection? And after how much time it will cause trouble?

Maybe: When health providers ask about potential risk exposures like blood transfusion prior to 1992, ever using injection drugs or home therapy like shared injected vitamins, sex with someone who might have had hcv, etc, we are trying to estimate how long someone has been infected. Studies show about 20% of people will develop cirrhosis in 20 years and rates increase the longer people are infected. ...Read more

No: About 25% of people who have hcv antibodies, indicating that they were exposed to this virus, will have spontaneously cleared the infection through their immune response. The only way to know if you actually have active infection is to test for hcv RNA (viral load). If the RNA is detected the person has active infection and could have liver damage. ...Read more

Can a carrier of hepatitis C transmit infection to his wife?

Yes: The risk of transmitting hcv to your wife is through accidental contact with small amounts of blood. Keep wounds covered. Do not share razors, toothbrushes, clippers. Of course do not share any injection drug equipment.
