They believe the epidemic will peak in Wuhan in one month and in China in two months. The rest of the world may not peak for 3-4 months. Limited evidence of impact of control measures to isolate severe cases because mild cases maintain the epidemic.
Takes up to 20 days or more to die from this. That's why China has such a higher death rate than elsewhere at present.
We still have a way to go.
