Even using the official Chinese numbers is scary- they say the death number is roughly 600 to date. 10 days ago they say there were 3000 confirmed cases. They say the incubation time is from a few days to two weeks. It would be most enlightening to know when the deceased were brought in for treatment- if they got infected 10 days ago that would imply a 20% death rate.
That might be optimistic. We actually don't know the number of deaths or infections, only what the ministry of truth tells us. They are almost playing a numbers game where Patient A had corona virus and died of heart disease, patient B died of a stroke, patient C died of cancer,, etc... A country doesn't isolate 50 million people because of a 100 deaths.
The cat is out of the bag now that a healthy Doctor in his 30s who was persecuted for talking about the virus just recently died.
I never worried about SARS, MERS, or bird flu, but this one has had me worried since day 1.
