Note: I work on NIH efforts to cure Long COVID called RECOVER, RECOVER-TLC, and help non-profits dedicated towards viral persistence/immune dysfunction hypotheses.
post-viral syndromes have been with us for a long time.
outside of very clear sequelae like definitive texbook case of autoimmune disease or something obvious like that - we don't really know how to treat them?
we now have novel technology being used like PET scanning, T cell biosensors, and single molecule ultrasensitive assays.
Antigen/superantigen persistence is shared and may be treated with extended courses of antivirals, monoclonal antibodies, immune modulators, and even trying checkpoint inhibitors to reverse T cell exhaustion.
the textbook is being rewritten and a key publication on how to treat at least Long COVID based on what I mentioned above will come out next week. NIH will launch their trials very soon likely announcing in March.
