explain 1(a)type and treatment viralload 8mil
Response from Dr. Holodniy
There are several subtypes of HCV. There are usually expressed as numbers and letters and this is based on the RNA sequence of the virus. Subtype 1 or 1a is one of the most common types in the US. Treatment is usually with an injectable form of interferon given once a week and ribavirin pills given twice daily for several months. Genotype 1 responds less favorably (about 40% having a sustained viral response) to treatment compared to say genotype 2 or 3 (60-80% having a response).
