Resistance of viruses to antiviral drugs.

ABSTRACT

In recent years, substantial advances in antiviral therapy have been made; however, in the immunocompromised host, antiviral drug resistance is becoming an issue of increasing clinical importance. Understanding the mechanism of action of antiviral agents, especially those used to treat herpesvirus infections, may enable us to design new therapeutic agents and better treatment regimens to deal with antiviral drug resistance.
