Welp,
@NIH RECOVER just renamed subset of Long Covid to PCFS, which stands for Post-COVID Fatigue Symdrome
"Essentially, it is the equivalent to the 2015 Institute of Medicine criteria for MECFS with two main exceptions. The Sx have to have started after a SARS-CoV-2 infection & Sx have to last only 3 months, not 6." -Hiten Niak
He's running the adult "Long Covid" (aka: MECFS) LDN trial. Don't meet MECFS criteria? You don't fucking count.
