Just an observation, but does anyone else find it curious that the hot, poor, densely populated countries with poor health practices and facilities, no travel bans and many people traveling there from mainland China (e.g. Chinese workers) have not experienced cases of the virus of any significance? Even poorer countries near China, like the Philippines, Vietnam, Thailand, Cambodia, etc have been able to avoid it.
What do these poor, hot countries have in common? It is the lack of, or at least relatively low levels of air conditioning.
At the same time the hot countries that are rich enough to have plentiful air conditioning, like Singapore and Hong Kong, have had significant spreads of the virus. Singapore publishes detailed reports on every single case (which the United States should do) and the virus had been transmitted to Singaporean residents only in air conditioned places.
The recent outbreaks around the world have all been in cool places: Northern Italy, Tehran and Seoul all still have temperatures in the 40s (Fahrenheit).
Gives us plenty of hope that this influenza will fade when the weather gets warmer. (But it could still spread in the Southern Hemisphere as the weather gets cooler in South America, Southern Africa, Australia, etc).
Note: These are just my personal unscientific observations.
CA is reported to have only 200 Kits and missed a diagnosis by many days because of the shortage and CDC guidelines in place at the time.
The Sudan...for example, doesn't have the sheer volume of daily international travels either.
It's probably a combination of many factors.
Hmmmn, perhaps it won't spread here in California. Solano County and Sacramento have warm temps. Here in South San Francisco temps are in the low 70s, it's been a warm February, and most people here do not have air conditioning (I don't).
The fact that you call a COVID-19 "influenza" discredits pretty any opinion you express about this coronavirus outbreak. Do not pass go, do not collect $200. Also, your claim that Northern Italy, Tehran and Seoul are "in the 40's" only applies at night, when people are indoors where it is much warmer. During the day when people are outside, they are currently mid 50's. And just as Singapore and Hong Kong have air conditioning, Seoul, Tehran and Italy have heat.
I doubt air conditioning is much used in Wuhan in January. Average high/low January temperatures in Wuhan 47°/33°.
