Virus Mutation Insights

Mutation is an inherent characteristic of RNA viruses, including coronaviruses, which possess some proofreading abilities that lower their mutation rate compared to other RNA viruses. Predicting mutations that would increase virulence is challenging, as viruses typically evolve to become less lethal to ensure their survival and transmission. However, the introduction of antiviral drugs or vaccines can create selection pressures that may lead to the virus evolving resistance or altering its structure to evade immune recognition.
