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.

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.

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.
