The CDC finally issued #ventilation guidance for buildings! 5 air changes per hour. To compare, negative pressure isolation rooms in hospitals have at least 12 air changes per hour. A standard hospital room has 6 air changes per hour. Dr. Griffin would love to see air changes per hour posted on public buildings to make educated decisions about #COVID risk. 1/
A rapid antigen #test (European Sofia brand) was studied in clinical setting. It was less sensitive for omicron and for ppl with lower viral loads compared to RT-PCR. Interestingly, more sensitive in men and older patients. Big takeaway is that we can’t really use RATs to screen for early asymptomatic #COVID cases anymore. Best time to use a RAT is day 2-3 of #symptoms…
…Not necessarily because the rapid antigen #tests are worse with #omicron, but because so many already have some immunity to #COVID (vaccination or infection) and our immune systems are trying to fight it off, lowering the viral load in the first few days.
People using #SSRIs were 1.3x more likely to die if they got #COVID compared to non-SSRI users. (Apparently people on social media were advising to take SSRIs just to prevent COVID??) The study was with Danish adults, up to 60 days after positive RT-PCR test.
(IANAD, but I’m sure if you’re already on SSRIs it’s best to keep taking them. The lesson here is don’t take SSRIs expressly to prevent COVID…)
