It's been a while since I've read a COVID19 preprint worth highlighting. I found one today that is *fascinating*
The study compares Delta vs. Omicron in terms of symptoms + rapid test results. Data was collected at a walk-up community testing site in San Francisco
Strap in. 1/n
They collected data from a HUGE study population— 63,277 persons over the course of 1 year (Jan 2021 to Jan 2022)
The other neat thing is that the testing site used the same eligibility criteria throughout and the same rapid test the entire time. 2/n
Another neat thing: the community testing site was located in a part of San Francisco that is predominantly Hispanic.
Yet another neat thing: they collected vaccination status.
Here's a link to the study for anyone who wants to follow along. 3/n
They found that symptomatic COVID-19 cases due to Omicron tended to experience cough (67%) and/or a sore throat (43%) and/or congestion (39%).
They also found that *fewer* persons reported fever and/or loss of smell/taste as compared to the Delta wave.
Another fascinating finding: fevers and body aches were *less* common among persons that had received boosters compared to those who received 0, 1, or 2 doses. 5/n
