We have now seen enough to replace the ocean analogy with a better one: wildfire. Like a wildfire, the virus relentlessly seeks out fuel (human hosts), devastating some areas while sparing others. We will achieve herd immunity either through widespread infection or an effective and widely available vaccine. In the coming months, US morbidity and mortality will largely depend on how much fuel the Covid-19 wildfire has access to. The level we need to reach is around two Sars-Cov-2 cases a day for each 100,000 population in a region.
