> It’s either the idea that this is a generally mild virus with some random severe cases and basically we’re all already infected, or this is going to be an endless, multi year spread and they’re accounting for that. It's partly the latter, but it's mostly just the result of exponential growth. The number of confirmed cases doubles every ~5 days, if that continues there are over a billion infections in 10 weeks. Whether it plays out that way or not depends on our containment efforts.
