No, the reaction is reasonable so far. 1) We know it's a fairly dangerous virus 2) We know it spreads easy enough 3) We know enough people get 'really sick' and require highly specialized medical intervention, enough that without controls it will totally overwhelm medical facilities. 4) We know that in order to stop the spread, you basically have to quarantine cities, shut down factories, have everyone everywhere wearing masks - have a look at Wuhan, it's like a ghost city. 5) The city went from a small number of cases to thousands quickly 6) Italy, Iran and S. Korea have seen small numbrers of cases explode and medical facilities are being overwhelmed in some spots. 7) Small numbers of cases in any country could easy grow into what we see in other countries. 8) The precautions taken in the West are mostly refusing travel from some areas, checking the health of others, focusing hard on those testing positive, ramping up testing abilities, getting the medical system prepared for the worst, trying to keep people from panicking. Corona is pretty scary - if it 'gets out' in America it's going to cause serious social upheaval and damage. It will be scary, especially because many people have no health insurance. A long term existential question will arise if America isn't able to treat those without coverage - it's basically untenable. If people start to die in any numbers in America because they don't have coverage, it will imply a major upheaval of healthcare in the country to the point wherein I think some kind of socialized medicine will have to happen.
