Detection of Hepatitis C Virus Resistant Mutants in the era of Direct Acting Antivirals

Hepatitis C Virus (HCV) infects millions of people and represents an important public health problem in different regions of the world. Drug resistance is a major challenge for HCV-infection related control. Importantly, the arrival of a plethora of novel, more powerful drugs has revolutionized the field of HCV treatment. Here, we discuss the relevance of identification of HCV resistant mutants from a clinical standpoint. The advantage and limitations of molecular testing in clinical setting is presented.
