  3. 1/ We are starting to get data on the age breakdown of the severe #COVID19 cases. While it’s true that if you just look at the mortality rate, it skews heavily to the elderly, younger people are definitely getting severely ill (they just don’t die in the ICU).

    2/ In Wuhan: 41% of severe cases were aged 15–49. “In truth, severe cases were slightly more abundant among this younger demographic.”

    3/ In Italy: “only” 12% of severely ill patients were aged 19–50 (less than a third of Wuhan). But Italy is now reporting a “second wave” with a noticeable increase in percentage younger severely ill patients. corriere.it/salute/malatti…

    6/ Why it matters? Many assume only the elderly are “at risk”. But if large numbers of young people get severely ill, we will (1) possibly have to contend with more long term complications including the heart & lung damage we are starting to see reported: scmp.com/news/hong-kong…

    7/ (2) have to re-evaluate assuming there’s no downside in infecting everyone except the very elderly for “herd immunity.”

    8/ The herd immunity idea also assumes immunity lasts a long time after infection, and we don’t know yet if covid is more like the flu, which (as we all have probably experienced) has no problem infecting the same person repeatedly.

    9/ A person infected with a flu virus develops antibodies against that virus; but as the virus changes, the "older" antibodies no longer recognize the "newer" virus, and the person gets sick again (hence the seasonal flu shots).

    10/ The SARS-CoV-2 virus that causes covid may well turn out to mutate like the flu and reinfect us seasonally. /end

    In summary: the assumption only the elderly are at risk from@#COVID19 is beginning to look misinformed. Teens and working age people make up a large percentage of the severely ill. The only group that seems relatively protected are children aged 2-9.
