in 3-4 days US is likely to become the first country in the world for no. of cases
I think on next Sunday it will get 200-300 thousands cases and around 3-4 thousands deaths
in 2 weeks deaths might probably exceed 10'000 and might even get close to 20'000

Death toll could still look like completely different in US vs Italy.
Italy has probably half million or more mild cases not tested whereas US testing is bit more up to date currently.
Age demographics has also huge difference for outcome: spread the virus to people mostly under 60 vs infect also everyone over 70.

mortality rate is not the same in all parts of Italy... somewhere it is almost 10%, elsewhere it is less than 1%
there are lots of factors to take into account and now it is too soon to analyze the data
in any case increase is slowing down (as percentage of previous cases)
today we had less new cases and less new deaths than yesterday
of course just one piece of data is not a trend

No DNA/RNA technology at that time. wrong
No advanced analytical methods and equipment at that time. wrong first ELISA test 1971, HPLC, MS-GC, PAGE all common laboratory equipment in 1980
No pneumonia/flu test at that time. wrong
No flu vaccination at that time. wrong - flu vaccines were available in the 1940s!
No internet at that time. right
No high-tech ventilators at that time. wrong
No CT scans and MRI at that time. wrong - first commercial CAT scanners 1972, first commercial MRI scanner 1980
No special antibiotics to cope with secondary infections at that time. wrong
No quality respirators FFP2-3 grade at that time. wrong
Fixed line telephones, sometimes a Fax. right
No personal computers at that time. wrong
Cold War [for GenZ and up - "Cold War" does not mean to "fight against commond cold"].. right

To be fair, whilst most of what he said was wrong, there are grains of truth here and there. For example, MRI scanners might have been on the market in 1980, but most hospitals wouldn't have had one back then, DNA sequencing was in its infancy, vaccines took much longer to develop, than they do today and personal computers were expensive and uncommon; I wasn't born until 1982 and I remember receptionists using typewriters, when I was a child: my mum used to have one and I had a toy one.

* Are they [facemasks] effective? Of course they are and even more so when grading goes up. There is a reason why they protect you from asbestos fibers or toxic dust. So they will protect your from infected particles or droplets.

The effectiveness of face-masks is nothing like as simple as you make it sound. What you say is not untrue but it is incomplete. FFP face-masks filter particles measured in micro-meters. The covid virus is measured in nano-meters.[/list]

AFAIK coronavirus diameter is 80-160 nm and FFP3 mask do filter fine particulate matter and do reduce the viral load
for that purpose (viral load reduction) FFP2 face-mask are considered effective too

Lots of things could have been done differently with a hindsight but so far the response in here hasn't been any worse than most of the countries with the Korea and Singapore being notable differences. China maybe also.

yes... we all have more or less bias...
I am much more biased than I'd like
sometimes I realize that and modify my posts :)
other times I'm so biased that saturate and my Vce goes down to 0nV :D

Good old X-ray is equally capable in confirming pneumonia.
