  • What is the relationship between mutations and COVID variants?

    Viruses like SARS-CoV-2 continuously evolve as changes in the genetic code (caused by genetic mutations or viral recombination) occur during replication of the genome. SARS-CoV-2 has consistently mutated over the course of the pandemic, resulting in variants that are different from the original SARS-CoV-2 virus.

  • Why does COVID 19 mutated to many variants?

    Just like the chameleons have evolved to change skin pigment shades to avoid predators, the COVID-19 virus evolves to avoid the human immune system.
    Virus mutation happens quickly over weeks to months due to the high number of viruses and infected people.

  • Why does COVID 19 mutated to many variants?

    Variants Are Expected
    Viruses constantly change through mutation and sometimes these mutations result in a new variant of the virus.
    Some changes and mutations allow the virus to spread more easily or make it resistant to treatments or vaccines.
