@a_onekatie, as @Kielanders points out below, we need to be governed by math and logic, not emotion and fear. Either we are totally overreacting to the flu this year, or we have totally underreacted every other year. 61,000 Americans died from the flu in 2017-2018 flu season and nobody suggested shutting down the nation. So far USA is at about 40,000 influenza deaths and well into the tail end of flu season, where heat and humidity greatly diminish the survival time of viruses outside the body, and contagion and new cases drop to near zero.
20,000,000 million around the world people die of breathing problems every year, only 2% of those (400,000 a year) are due to the flu. There are 100+ active flu strains in circulation right now like there are every year, but most kill anonymously because we haven't yet named them or developed a test. The latest information is that COVID19 has likely been in circulation since at least November, and about 7% of Americans (23,000,000) would probably test positive for it right now based on U of Washington testing of the general population. There is no reason to freak out as every new case is revealed as this is just documenting the progress of testing, not the progress of the disease.
Current official estimates of the contagiousness of Wuhan Flu from WHO, CDC, and ECDC put its R0 at 2-3.1, which is slightly above the regular flu, but below SARS, MERS, Norovirus, Zika -- none of which made a big dent in annual flu deaths or forced nations to shut down.
What the media and politicians won't admit is that initial outbreak estimates of any newly-identified pathogen are always orders of magnitude too high because early testing is confined to the dead and sick in morgues and hospitals. Based on past years' CDC data, on average a hundred million Americans are exposed to the most common flu strains and would test positive if we did the testing, tens of millions get sick from them, and about 40,000 die from them.
So far we've had about 30,000 deaths from anonymous flu viruses, but we are giving all our attention to a charismatic new bug that has only killed 16,365 in the whole world, and 590 in the USA. Hoping POTUS orders the nation back to work and back to school next Monday. Else, many more people will die from hunger, energy poverty, domestic violence, riots, and suicide than from Coronavirus.
