I like your optimistic spirit. Not 20 times more deadly, only 10 times more deadly. If we do enough mass testing, maybe we can get it down to 4 or 5 times as deadly. It won't help the dead or their families, but if it makes you feel better, more power to ya. You're probably a fairly decent person in the real world.
10 times nearly zero is still nearly zero. But if you focus on the numerator without considering the denominator then you can make insulting allegations.
Go get a 5th grade math book.
Haven't done the math in last 3 days, but doesn't take a mathematician to know that more people tested will raise the denominator enough to outpace the numerator, but nobody but you thinks it is going to get down to the morbidity of the 4 or so more common Flu viruses (combined) that we are and have been mass vaccinating against for years. Stay safe in you home school math class, wash your hands, follow the advice of the president (when he is on script, not talking off the cuff), avoid crowds and don't eat the chalk for you blackboard. It ain't a peppermint stick.
Again, the flu is not nearly as selective so the comparison is moot.
Time to stop throwing the baby out with the bath water.
If you are saying that Covid-19 is much more infectious than any of the standard flu viruses we deal with on a yearly bases, you are correct. Throw baby out with bath water? Well, infectious rate for babies and children is in fact very low, but I would simply make sure to wash their little hands regularly and keep them away from other groups of children, run the bathwater down the drain and clean the tub or sink using a disinfectant spray. The threat is not moot yet and not expected to be anytime soon. Bye the way, Medium.com seems to have shut down the link you supplied, supporting (poorly) that other thread you started to downplay the Covid-19 world pandemic, and have put the post you sight under investigation for breaking Medium.com's standards. Which is really a shock, coming from medium. You will simply have to improve your sources.
