The rate of death to recovery varies by country, and I’m sure a big part of it is how many people get tested (the more widely available the tests are, the more people who will recover vs die).
In the US I think we only test the worst of the worst cases. Our ratio is about 1:2 when it comes to how cases resolve. If you have 3 cases, about 1 will die and 2 will recover of our confirmed cases. As of today, we’ve got about 40k deaths, 78k recoveries. I think the 1:2 ratio has been fairly constant for several weeks. So are we looking at a 30% CFR in the US because we only test the worst of the worst?
Problem is, we’re currently at about 800k confirmed cases and still gaining ~30k cases a day. However our rate of new cases seems to have stabilized at about 30k cases a day for quite a while, probably due to a lack of testing.
Death rate has been stable at about 2k deaths a day, but seems to have jumped to nearly 3k deaths in one day yesterday. I don’t know if thats a continuing acceleration or if the rates are constant.
