Coronavirus Replace #56 – This audiocast is a deeper dive into covid and kids’s psychological well being.

For my part, our kids’s psychological and bodily well being have to take primacy over pandemic concern presently. We’ll dive deeply right here. Additionally, Omicron’s sibling is the brand new variant BA.2. It seems to be very similar to Omicron from the identical lineage genetically with 50 amino acid adjustments. It’s extra infectious by 10-30% by most up-to-date information. No information that it’s extra lethal thus far in people though a preprint article from a Japanese analysis group famous that in an animal mannequin the illness is worse than BA.1 Omicron. (Yamasoba et. al. 2022) They famous extra mobile fusion rising infectivity and in addition extra lung cell an infection rising morbidity. The immune safety from BA.1 in opposition to BA.2 was diminished by 6X. This doesn’t imply that people will reply the identical manner because the animal mannequin outcomes. It bears watching. Thus far, I’ve seen no information that people are struggling worse illness. United States BA.2 numbers stay lower than 10% seemingly as a result of high quality immunity achieved following the huge Omicron BA.1 surge the previous 8 weeks. Our T and B cell immunity from BA.1 ought to serve to guard most of us from any points with BA.2. Time will inform, however up to now so good.
