Speculation:
Nipah virus was smuggled from Canada to Wuhan. It causes fatal respiratory failure and brain/neurological symptoms. Fatality rate is 70%
Seems to enter through Ephrin receptors, which I know jackals fuck about, but I will research.
Interesting part here, my guy in Shanghai back in January 2020 said the Chinese were aggressively banking on Remdesivir, both with patents and total supply control. Cover story was Covid, but it appears to suck against covid.
What IS it effective against?
Nipah.
