Hi, My name is pomaa and I am from Myanmar. One of my friends is suffering from hepatis C genotype 6n. His liver condition is fine and there is no cirrhosis according to the doctor. For that, he was prescribed sofos 400mg plus robavirin 1000mg for 6 weeks. After 4 weeks, 12 weeks, 24 weeks, SVR is good. After 3 months completion of teeatment, the virus become appeared again. Can anybody give some ideas how should I suggest to my friend? Thank you so much.
