If you add up all of the infections in the EU, you get numbers similar to the US, and test results are very situational. If you get tested in a state that doesn't have an outbreak, it'll go faster than one that does. The US Federal government doesn't have the authority to swoop in and play hero in the same way the EU itself can't come in and dictate to Germany what they must and must not do. For the US, habeus corpus among other laws and our constitution are reasons why. What the federal government has done is print money and hand it to the states and people directly which IMO, is a solid initial move while all the other machinery is brought to bear.
Never discount a European's willingness to poo-poo the united states. It's like a pass time.
As for data.
Peer Reviewed Antivirus\Seriological studies show a mortality rate of .9-1.1% when hospitals\ICU's are not overloaded. When they are overloaded, the observational data shows that rate jumps up to double digits. Something like 30% of patients require hospitalization. There's also a body of observational evidence this virus also reinfects people; GISAid shows 6 distict strains at this point.
So your enemy looks like it can infect and reinfect and every round, if your healthcare system isn't built up, it kills double digits.
India has an exponential breakout they will not be stopping any time soon, Brazil is following suite it seems as well. It doesn't require a lot of scientific infrastructure to count body bags and the fundemental reason the numbers are so f'd up is due to the fact once body bags begin piling up people freak out and try something new.
If you are smart you'll take this thing seriously, wear a respirator or CBRN Gas mask, and work at getting yourself healthy.
