There is an element of seasonal roulette with emerging viral diseases.
I have previously said #OnHere that China had a stroke of bad luck to have emergence in December, just as the flu season was getting underway.
But there is another reason: flu and *all* respiratory viruses spread more in the wintertime.
Even measles — a rash, but which has respiratory transmission — is winter-dominant.
Getting back to the matter at hand, #coronavirus #nCoV2019 #COVID19 and the timing of its emergence...
It's now mid-February. The days are getting longer in the N Hemisphere..
The timing of emergence was about as bad as possible, but we are heading towards spring.
(1) In China... as bad as it is, the seasonal change is heading in the direction of making things better. Hold on, spring is coming! Viruses become less transmissable in the spring/summer vs. fall/winter.
I'll leave it there for now. Thank you for reading this thread on #seasonality and respiratory-virus epidemiology. #pandemic #CoronavirusOutbreak #COVID19 #coronavirus #preparedness
