Bogus. WHO was talking 3.4%, but even that's probably high. Here's off a Yahoo News page:
Since the COVID-19 outbreak began to pick up steam in China in January, experts have been scrambling to get a handle on the disease and the way it behaves. But they have also warned that estimates are not exact, and that numbers are likely to shift over time. One key reason: people with milder versions of the illness are underrepresented in official case counts, since they may not be sick enough to seek medical attention or realize they have anything more than a cold. Some people, research now suggests, may get infected by SARS-CoV-2, the virus that causes COVID-19, without showing any symptoms at all.
That means the total number of reported cases is very likely an underestimate—and by not counting many mild or asymptomatic cases, we’re likely overestimating the disease’s overall mortality rate.
