There's been a lot of general questioning of how reliable the numbers coming out of china are, but honestly, it's an evolving situation, and probably nobody really knows for sure.
However, WHO personnel are in China now, and the most recently released numbers shot up to 59,493 cases, 1353 deaths. I believe they changed some of the criteria and are allowing clinically diagnosed cases to be counted, not just rt-PCR lab confirmed cases.
China state media declared martial law for the next 14 days in Shiyan, a city of 3.3m people. No private vehicles are to be on the road, and no civilians are permitted to leave their residences. Anyone attempting to leave their residence will be arrested.
