There are 48,206 confirmed closed cases of 2019nCoV. The actual number of total cases is certainly higher than this, maybe 3 times higher.
3,057 of those outcomes were death, that is 6%. It would be very hard to miscalculate this. Deaths are always reported -- ok well we could argue this point since we're talking about the CCP -- but I think the margin here is probably pretty small.
Fact is, you could rule out any fatality rate above 6% categorically. It's likely very close to 2% based on scientific models and two peer reviewed epidemiological studies, one in the Lancet and one in Los Alamos. Models which place the CFR blow this are based on the notion that many more people have been infected than have been reported. A 1% would mean more than 300k people have been infected and not the 90k reported by the WHO.
