Just how effective the outbreak seems to have been contained is astonishing. Publicly available data can be employed to estimate the attack rate of the COVID-19 outbreak in China. There are two datasets with a very different picture of the same epidemic caused by the same virus [3].Data from Hubei (roughly 80% of the China outbreak with a focus on severe cases and high case fatality rate (CFR), currently cumulatively estimated to be around 4%).
Data from China outside Hubei province with a probably much better coverage of the whole epidemic due to active case finding.
