"Getting COVID Again Is More Dangerous Than Most People Realize—Here’s What To Know"

"Each COVID-19 infection is a new stress on the body. Repeated infections may increase the risk of long COVID by cumulatively affecting the immune system, inflammation and organ systems."

"What makes getting long COVID especially dangerous is that there is currently no cure for it."

@DenisCOVIDinfoguy Any time I've known I was exposed, I tested. I was vaccinated till I stopped being able to get the boosters. I have never had a positive test. Is there a way to test if I've ever had asymptomatic covid?

@hellomiakoda @DenisCOVIDinfoguy In theory, your vaccinations should have given you antibodies against the spike protein, but not the nucleocapsid protein, whereas an infection would induce both. So a test that measures S/NC antibody ratio should be able to distinguish between vaccinated/never infected and vaccinated/infected (even if the infection did not cause symptoms). Some US labs offer such tests:

@hellomiakoda @DenisCOVIDinfoguy In practice, I'm not aware of any studies aimed at testing this hypothesis, nor would I be 100% confident in interpreting the results of such tests.

When I worked at Thermo (spit!) we had tests which could measure the S/NC ratio. The devs couldn't point to a bright line between un/infected against a vaccine background, but that just means it wasn't obvious at a glance. I could never convince corporate to run a proper study and publish it.
