I’ve been tanking some downvotes for the past few days for saying this. Disease spread is only exponential for a brief initial period. It is not a good mental or even general model for how disease spreads. We have two years of observational covid data that shows this to be true.<p>Spread slows down rapidly long before reaching 100%. People hear “5x as infectious” and reason that due to the nature of exponential models, that much more than 5x people will be infected. This is extremely incorrect. In truth, far fewer than 5x people will be infected over the long term. And again, no, this is not because it’s hitting the upper limits of 100% of the population or anywhere near that.<p>I won’t be so bold as to say it’s probable, but given this is not a novel virus, it’s entirely believable to say that omicron could go on to infect fewer people than delta due to the past two years of vaccination and immunity and die off. Presuming data about lower severity holds, it would be surprising to me if hospitalization or deaths aren’t noticeably lower than delta; which, in turn, was noticeably lower than the original.
