That's because most reputable sources don't have enough information to make a reasonable estimate of the case fatality rate. The JHU map only shows raw numbers.

If you're using deaths as a proportion of known outcomes, Hubei has come down to about 35%. Other provinces are reporting, at most, six deaths. I don't believe the numbers coming from China for one bit. Yes, Hubei is overwhelmed, but it really wouldn't take much to overwhelm most health care networks (in- or outside China).

Dutch wire service BNO News is reporting that a Japanese national who died in Wuhan was believed to be infected with the coronavirus but not included in the official coronavirus death count.
