My second question: I have a friend who had Hepatitis C which was detected about 15 years ago. She had treatment in Japan and then in the US for totally about 2.5 years (2 years in the US). Finally the doctors gave her a clear report, saying that they did not see any viruses anymore. She is happy now. But She and i are wondeirng if the viruses are really gone as we heard that they might still hide somewhere in human bones or bone marrow and elswhere in the body and can get strong again! Is this true? Is making sex with her without a condom OK? Is deep kissing her OK? Is swalllowing her saliva OK? Her clearance report was about one or two years ago.
