Huge two week jump in Covid cases

The huge jump in Covid-19 cases over the last two weeks shows how quickly the virus can spread.

The US in particular – up from 4,632 cases to 101,657 cases.

From CNN One nation, under coronavirus: How two weeks changed America

That’s up until 27 March and is already out of date. Current totals (it’s just into 28 March in the US so about a day later) from Worldometer:

  1. United States 123,750
  2. Italy 92,472
  3. China 81,439 (that’s down a bit so must be different source)
  4. Spain 73,235
  5. Germany 57,695
  6. France 37,575
  7. Iran 35,408
  8. United Kingdom 17,089
  9. Switzerland 14,076
  10. Netherlands 9,762
  11. South Korea 9,583

Only China and South Korea have low changes, they rest climbed alarmingly over the last two weeks and a day.

But these numbers are understating the actual infection rate, in some cases potentially substantially. For example:

Italy’s number of confirmed cases is “not representative of the entire infected population,” said Dr. Massimo Galli, head of the infectious disease unit at Sacco Hospital in Milan. The real figure was “much much more.”

Some researchers estimate that up to 80% of people who are infected show no or only mild symptoms and may not even know they are sick. That would put the number of people who might have been infected in the millions. But we need many more studies and much more testing to close in on a more accurate number.

    This could be a game-changer – using blood plasma from recovered patients as a vaccine short circuit for seriously ill patients:

    Imagine that 85 and up age group is a thing
    Who are those people saying it’s not primerly affecting the elderly, just like flu and pneumonia

    We will never know ‘the numbers’
    Apparently 5 years after the Sars outbreak of Covid they still couldn’t agree even fir that event.
    Having the actual numbers means there is winners and losers in the medical prediction industry and the Charleston’s exposed.
    I guess we won’t have a consensus with covid 19 either for the same reasons, but the graphics tell us enough
