One to watch very closely, I think...
The suspicion is that there are a lot more than the confirmed 62 cases in Wuhan, mostly supported by the numbers (though small) of confirmed cases in travellers (2 in Thailand, 1 in Japan, as of Friday last week). Colleagues at Imperial College have estimated somewhere between 427 and 4,471 infections. Clearly, if this is the case then it appears to be relatively mild compared to SARS, but suggests that human-to-human transmission is ongoing and sustained. Control is going to be very difficult if infection is largely sub-clinical (ie, people aren't sick enough to present to health-care services where they can be identified as a case). Even if the fatality rate is low (relative to SARS and MERS), if we see a big enough epidemic, it could still make a nasty impact.
I suspect we will see more cases in travellers to other countries, further investigations in Wuhan may reveal the true size of the outbreak, and we'll see outbreaks in other provinces in China.
