What is thought to be known about this coronavirus/Wuhan Pneumonia, so far:
The outbreak began in Wuhan, China. Population ~11 million. The city is now under lock down.
According to the CDC the risk to the general American public is considered low at this time.
In it's early stages, a minimum of 500+ people have been infected according to the Chinese government, although many believe this be grossly under reported, and that the true number is in the thousands.
17 dead,
That H1N1 virus mutates a lot--not like the SARS-COV, which has mostly mutated just along the spike protein. This is why the vaccines are proving more effective against the variants--the vaccines all focus on the spike protein.
Also in 1918-21, 1/3 (!!!) of the human race caught it (herd, massive variant possibilities) and that H1N1 flu's direct descendants still rise up every once in a while on grand scale, 2009 being the most recent bigger moment, and are in circulation every year.
