COVID infection increases clotting risk.

New study: Blood from unvaccinated people after recent COVID was more hypercoagulable, and their plasma corrected low clotting (INR) in recipients.

This pro-clotting state can persist for ≥6 months after infection.

This is maddening.

I'm glad that California, Illinois and NYC have joined the WHO's Global Outbreak Alert and Response Network (GOARN) though. buff.ly/NbMdvEp

GOARN gives global early-warning alerts on outbreaks, and collaboration and support during major public health emergencies.

I think that it was an observation they had that the recipient's blood was now clotting normally. The graphic may not show that clearly.
It is very concerning though that the donor plasma may affect the recipient. I assume that the donor blood was tested and was negative for virus.

A huge study from Kaiser Permanente Nor Cal of 69,987 children shows that maternal COVID infection increased the risk of autism by 44% for girls, but not for boys, especially if the infection was in the 1st or 2nd trimester. buff.ly/4tj7zSp

Why are certain immune cells affected in COVID and Long COVID?

Viral fragments of SARS-CoV-2 called xenoAMPs target specific immune cells based on the cell’s geometry. buff.ly/iWpGOPB

✴️Spiky dendritic cells and T cells are destroyed.

🟠Round monocytes and neutrophils are not.

It's really appalling that in the midst of a preventable surge of measles sweeping across several US states, leading national health authorities are not loudly and publicly recommending vaccination.
How many more children need to die for this madness to stop?

Thank you President Jimmy Carter for supporting the eradication of this disease. Amazing!
Only 10 cases of Guinea worm disease were recorded *globally* last year.

It may become the second human disease we eradicate, after smallpox.

Monoclonal Antibody (mAbs) study buff.ly/UyotGQZ

😀mAb decreased need for oxygen in high-risk patients

😀mAb not later linked to Long COVID, CV disease, or cognitive decline

☹️mAbs use for acute COVID led to >2x risk of new autoimmune dz like Lupus & Rheumatoid Arthritis

The more that I learn about the gut – brain axis, the more I understand about post-infectious conditions like Long Covid.
