(It helps to be a small island nation with a major genetics country.) Of the 1618 confirmed (as opposed to estimated like the CDC/health departments are doing here) cases that have gone to completion, there have been 10 deaths. That's a case fatality rate of ~0.6%.

Of those 10 deaths, 1 is for someone less than age 60. That's a case fatality rate of 0.075%. For individuals aged 60-69, the case fatality rate is ~1%.

There are some negative things that have come out of their study. Approximately 1/2 of the infected individuals are asymptomatic. That highlights how ineffective our approach of testing symptomatic individuals is--with a false negative rate of 30% you gain almost no information by testing a symptomatic person. (It the test is positive, you learn that your suspicion was correct; if the test is negative, you still need to isolate the person because of the false negative rate.)

This is a serious illness because of (1) how infectious it is, (2) the high percentage of asymptomatic individuals, and (3) the fatality rate for older individuals. However, the facts indicate it's not nearly as serious as many continuing government actions would indicate.
