Age x Obesity + Degree of Infection => Aerosols Released
The equation above oversimplifies, but it captures the gist of the findings. Basically there are a few people who are superspreaders, and the scientists are starting to understand who and why. In their words "exhaled aerosol particles vary between subjects by three orders of magnitude, with exhaled respiratory droplet number increasing with degree of COVID-19 infection and elevated BMI-years. What this means to us is that it is still reasonable to keep staying away from most people, keep wearing masks, and find a way to lose weight if you've gotten fat. I've got friends who've had great success with Noom, and others who swear by the Ketogenic diet or the Whole 30. But there is no doubt that obesity is a huge risk factor for bad outcomes and also for being a superspreader.
