At the onset of infection, poxvirus particles attach to the host cell membrane through various viral-host protein interactions. WebAug 13, 2024 · RNA viruses have high mutation rates—up to a million times higher than their hosts—and these high rates are correlated with enhanced virulence and evolvability, traits considered beneficial for viruses. However, their mutation rates are almost disastrously high, and a small increase in mutation rate can cause RNA viruses to go locally extinct. churro wedding
