Wuhan hit about 17% in the early days when their hospitals were overloaded. I though that was common knowledge? I also thought it was common knowledge that about 1 in 5 symptomatic cases require medical care.
The cdc has revised their estimates down in wuhan from 17% to 12%, and hospitalization rates have also gone down as testing has improved over the last few weeks. On the flip side there is mounting evidence that many COVID-19 deaths are not being counted.
