It's too early for data on this coronavirus. There isn't enough organizational capacity in Wuhan to properly capture the numbers; to start with it's difficult for people to get to the hospitals because transit is shutdown, and if they get there it's often pointless because there are very few test kits and no free beds. How many have been infected is impossible to determine.
