The numbers start going down quickly once infections have been so prolific that crowd immunity is present.

I live in Texas, but I'm sure I personally infected no fewer than 10,000-20,000 people last March, including the sorority that purportedly brought it back from Mexico during spring break. No doctor wanted to listen and no hospitals would test me even after I begged some of the best providers in the region. It wasn't until almost 9 months later that the mistake was acknowledged, and it's highly likely that community spread existed even in the US in November 2019 or even October 2019 just based on retrospective serology studies.

Places with poor hygiene controls like India have likely had far, far more infections than anyone even can imagine. That might be one of the first places to be immune.
