Well that's a tough one to answer. Perhaps a combination between contagion rate and recovery rate? Man people are dumb. Can't see something until it's right in front of their face. In another 2 weeks it will be impossible to deny. Unless that medication is as good as they say in the comments of that tweet.
According to
data from this site, flu results in hospitilzation about 0.7% of the time based upon estimated 200,000 flu hospitilzations most years and estimated 10-50 million flu illnesses each year (roughly 10% of population).
Average length of stay for flu hospitizations is 5 days.
For COVID-19 thus far in the US,
12% of known cases have been hospitalized. Data from China suggest
5% of patients reach "critical" status, with 14% of cases being considered "severe". I don't think that is an apples-to-apples comparison as it is estimated data vs. confirmed data. We will probably have to wait until this is all said and done to get a true sense of the comparison. Average COVID-19 hosptial stay is tough to pin down at this point, but
preliminary data from China indicated a median 11 day stay to discharge (mean 9 day stay for those who died).
So that, combined with estimates that 20-60% of the population could come down with this, and the dramatic rate of spread (
greater than influenza), suggests that this has the likelihood to get much worse than the relatively spread out flu season.
But as I said, there is some "apples-to-oranges" comparison going on there.
But if we just look at some recent data from New York: r
oughly 180 weekly deaths from influenza & pneumonia for each of the weeks ending in Feb 29, March 7, and March 14. In the 2 weeks since,
COVID-19 has resulted in over 800 deaths in New York.
Rate of hospitalizations from all causes has increased 13x in the last 10 days in New York City.
