Viral Genome Replication Fidelity (VRF)

Viral genome replication fidelity refers to the accuracy with which a virus copies its genetic material during replication, primarily determined by viral polymerase enzymes (RdRp, DNA polymerases). It impacts mutation rates, adaptability, and genetic stability, influencing viral pathogenesis, vaccine development, and antiviral strategies. Modulating fidelity is a potential therapeutic approach.

Mutagenic drugs increase error rates beyond the virus's error threshold, leading to population collapse; some antiviral drugs act as base analogs that either increase error rates or select for higher-fidelity resistance variants among target pathogens.
