This coronavirus seems uniquely adaptive because of the incredibly high viral loads that are found in both vaccinated and unvaccinated people. Every copy of the virus carries the risk of a new, more dangerous variant.
Other viruses are not currently or historically infecting millions of hosts every day. When there's a million people infected every day the chance of a worse variant is a million times higher than if there was 1 case a day.
