No it's NOT hysteria. Every government on the face of the earth is spending billions of dollars to stop this. They ALL (including our government) instituting mass quarantines. They are banning travel to and from affected regions. They are locking down entire cities and areas to prevent new cases.
They are doing this BECAUSE 15% to 20% of everyone who contracts this disease NEEDS hospitalization. Our of this 10% require ICU.
IF this ONLY spreads as much as a mild flu season then there are not near enough beds by a factor of ten times to handle it in US. It will crash our healthcare system, bankrupt doctors, hospitals and individuals and generally cause economic chaos.
Say whatever you want to believe this is absolute hysteria!!!
