I follow this epidemiologist, who is generally quite informative and links to useful resources.  Note his alarm about the situation in Seattle, also his criticism of the W.H.O.'s idiotic announcement of a fatality rate of more than 3% for the virus.   In dysfunctional countries, like Iran and the U.S., which aren't doing enough testing, the case fatality rate looks like it's 3% and 8%, respectively, but that's because they're doing a terrible job testing people.  We know that in China, the rate in Wuhan was quite a bit higher (over 4%) compared to the rest of the country (under 1%), mostly explained by Wuhan being overwhelmed and caught by surprise in the early stages.   By contrast, South Korea, with its aggressive and widespread testing, has a fatality rate (so far) of about 0.5%.   Singapore, with more than 100 cases (they too have done a good job controlling further spread), has no fatalities.  The rate for the "Diamond Princess" cruise ship is about 1% to date, remarkably low given the petrie dish of disease that was created.
