Karl Denninger has a good explanation. The only way this could have happened is if there already was a high level of immunity. Korea did not shut down their whole economy and their cases are leveling off, not growing exponentially like Newsom and Cuomo are hoping for.

The explanation is that this is a variant of a virus that has been around a long time and that 90% of the population may have already been exposed to it (through your dog or cat?). Some recent mutation might have made it more deadly to a sliver of the population, but it would be continuing to grow exponentially in China and Korea if there wasn't a high level of natural immunity.

No data, it's a crapshoot.

thought the same too

I don't believe anything they say, but it is true that eventually an epidemic runs out of new hosts and then it all crashes. This is why social distancing helps, and a few people getting out of the "distanced" group will cause new outbreaks in a previously clean population so the duration of the epidemic is longer. It could be that so many people in China were infected early on that most of the population got sick at once, with a huge spike in deaths, and that means they would also mostly get well at once.

I thought i read an article saying pneumonia is spiking like crazy in China
