    Your terminology is wrong. "COVID19" could never be a novel virus simply because that's not the name of the virus; that would be SARS-CoV-2 (COVID19 is the disease caused by that virus).

    And flu is flu; it's caused by influenza viruses. Coronaviruses only cause conditions that we would consider part of the "common cold" set.

    Regardless, SARS-CoV-2 *does* have some novelty. No cold viruses, and very few flu variants, have had such a high degree of lethality. Although about 600,000 deaths have been officially attributed to COVID19 in the U.S., we've had 920,000 more people die in the past 18 months than would be expected from statistical trends. Most of those must be COVID19-related.
