  Fauci said, "This means that the new crown virus will not disappear from the population for a long time."

  Fauci explained that this is mainly because the new coronavirus is prone to mutation. In the past two years, five separate variants, including Delta and Omicron, have appeared.

Second, not enough people are vaccinated, and the non-persistence of immunity also contributes to the persistence of the new coronavirus.
