Michigan now at 1800 known cases with 24 deaths. Mortality rate = 1.3%
You can't calculate a mortality rate from those two figures.
Not until all known cases have resolved.
Actually, that's what I've been saying all along.
Until you test everyone, you dont know. What we DO know is the mortality rate is MUCH LOWER than this figure, meaning it's time to get back to work!
There are currently 55,000 cases in the US today. New cases are increasing by 25% to 40% a day. Assuming only a 25% increase, there will be approximately 3.8 million cases by Easter with 49,000 deaths if the current rate of increase does not change and mortality rate is 1.3%. If the cases grow at the current rate, within 3 weeks our hospitals will be overflowing, similar to that in Italy which has a mortality rate of 10%.
If we are successful at isolating people then it could be a lot better. However, if we significantly decrease isolation, logic tells us it will be a lot worse.
I'm sure you and a lot of other people don't believe any this but consider this. On March 4th, just a little over 3 weeks ago there were 5700 cases and 35 deaths in half dozen states. If I had said in 3 weeks Covid 19 will be in every state, there will be 55,000 cases, 670 deaths, you certainly would not have believe it.
