Early treatment of infection is the key to preventing bad outcomes from covid. If you know an elderly or otherwise immunocompromised individual, be sure they know how to find a nearby monoclonal antibody infusion center.
It’s a simple procedure that takes under an hour, followed by an hour of observation. There’s no requirement to be seen by a physician (and can only be administered to individuals who have NOT been admitted to the hospital).
Receiving the infusion should be one of the first steps after a positive covid test, or presumed infection, for any individual who does not have a young, healthy, and robust immune system. This is likely applicable to anyone over 55 years of age without a known recovery from SARS-COV-2.
