Good advice.

There is an article at: Novel coronavirus 2019-nCoV: early esti...mic predictions The key findings relates to the transmissivity of the virus. Any number over 1.0 indicates that the virus won’t go away on its own. The number in the article is estimated at 3.6 - 4.0; other numbers I’ve seen have been lower, 2.5 - 3.4. Both ranges are over 1.0 though which means nCoV won’t die off on its own.

Those numbers are necessarily estimated out of the infections in China, where it was allowed to run wild (for weeks) before any serious steps were evident. The human-to-human infection in the United States was between a husband and wife who apparently took no preventative measures. First human-to-human nCoV spread reported in US
