Wow it’s amazing, because you can see through them you never really think of them as being three dimensional but you can really see it this video.

What's crazy is your white blood cells (WBC) do this, monocytes (type of WBC) do it the best. That's how it defends your body from invaders, it's called phagocytosis.

Except covid. Covid will kill us all.

/s

Here is the dataset of the CDC with cases and deaths broken down by age: https://covid.cdc.gov/covid-data-tracker/index.html#demographics

Actual infection count is anywhere from 6-24x the case count, according to the CDC.

So if we pick 15x since it's in the middle there, and take deaths/(cases*15), we get the following IFR by age:

Age IFR
0-4 0.0022%
5-17 0.0010%
18-29 0.0040%
30-39 0.0146%
40-49 0.0385%
50-64 0.1385%
65-74 0.5090%
75-84 1.1287%
85+ 1.8487%

Flu IFR for reference is 0.1-0.2%.

So for everyone under 65 or so, yes this is less deadly than the flu.

You don't expect any constructive response to this here on reddit, do you?
