Before revision:  Case Fatality Rate is five times larger in Hubei, but our estimated Infection Fatality Rates  are much more uniform/consistent across all provinces. Therefore, interplay of transmissibility, effective protection, and detection efficiency differences may explain apparently drastic count discrepancies .
After revision:  Case Fatality Rate is five times larger in Hubei, but our estimated Infection Fatality Rates are much more uniform/consistent across all the provinces. Even for Wuhan, our inferred Infection Attack Rate is much below the herd immunity threshold, raising a major reemission risk. The obtained results demonstrate applicability of our developed method to extract key infection parameters directly from the data (publicly available for a number of countries), so that it can be applied globally to potential future outbreaks of COVID-19, or other infectious diseases .
