A few scientists early on suspected that Covid-19 damage important parts of the immune system in a way that opens up for other infections and cancer. They were right.

Many, not only long Covid patients, experience so called brain fog after being infected with SARS-Cov-2. Now scientists at Karolinska Institutet have discovered why: broken connections in the brain.
More and more proof sees the light of day that Covid-19 at least to some degree affects T-cells and either kill them or exhaust them. This is bad news as we have a finite number of T-cells and it also means that the more Covid-infections we have, the fewer working T-cell we will have.
48% has remains fatigue after covid. That’s a lot. To put it short.
Both children with long covid and those considered fully recovered showed reduced lung capacity after covid. Both ventilation and perfusion (oxygen getting through to the blood) showed significant decrease compared to the control, group. Albeit a small study, this tells us that Covid-19 is certainly not harmless for children and that a large percentage contract lung damage even in mild infections.
It is kind of obvious that mask should make a difference. especially if we are talking respirator masks (N95/Ffp2/Kn95 etc) that are designed to protect the bearer from patogens like viruses. What we have sort of lacked is a real world comparison between a larger number of schools that keeps mask requirements and schools that remove mask requirements. And the result is clear: it makes a big difference. The first link is to the Time article about the NEJM published study.

Yep. Once again, mild acute infection doesn’t mean your out of the woods; it is still pretty likely you will end up with brain damage. Enjoy…
Air-Cleaners & Ventilation Matters!

This important study shows the importance of excellent ventilation! This pretty much confirms the results of a number of smaller studies including those with Corsi – Rosenthal boxes.
This is of course applicable to offices and other indoor settings as well. Ideal is of course to improve ventilation, but air-cleaners can be a viable solution as long as you get the air filtered at least 6x per hour, as shown in other studies (link coming soon).
Combining the air cleaners with FFP2/N95/KN95 masks would likely stop spread of the virus in the setting pretty much 100%. Even with super-spreading variants of Omicron BA.5 and later dominating.
This overturns all the desinformation from big players like the Swedish Public Health Authority Folkhälsomyndigheten and Koch sponsored desinformation machine Brownstone Institute.
First the link to the Reuters article, second lik is to the study itself.
