CDC no longer recommends universal masking in healthcare facilities unless local CoV-19 transmission is high (>/= 100/100k/7d). This is a problem for several reasons. But first, most of US has high transmission currently, so no change at the moment. 1/

Despite the most unwelcome Omicron surge, there is good news: vaxxed/boosted have excellent protection from serious illness. Omicron will pass & things will improve. We can limit its damage. I'm looking forward to, & wishing all, a much better, healthier, & more peaceful 2022.

To determine the risk, you need to know how frequently these outcomes occur in vaccinated & unvaccinated groups (the rates of disease in each group). To compare most accurately, we should compare vaccinated & unvaccinated people of similar ages (adjusting for age). 2/

What does this mean? We need a vaccine-plus strategy to prevent CoV-19: updated boosters, improve indoor air, masks in public spaces, widespread access to testing & treatment, good surveillance. This is not the time to relax these simple precautions.
