Research published today in Lancet Infectious Disease and supported by PolyBio Research Foundation provides the strongest evidence yet that the COVID virus can persist for months or years after infection. The findings, published by a UC San Francisco/Harvard Medical School team, found that proteins created by the virus were still present for up to 14 months in a quarter of people tested. This demonstrates SARS-CoV-2 viral persistence as an urgent area of research underlying a breadth of chronic disease after COVID.

“The fact that every new SARS-CoV-2 infection has the potential to become chronic is perhaps the single most concerning aspect of this virus” says Dr. Amy Proal, President of PolyBio. “We have compelling data that viral persistence is much more common than recognized which could have major health implications.”

However, with an estimated 18 million adults and 5.8 million children suffering from Long COVID, government investment is also needed. SARS-CoV-2 has even been found in the lymph nodes of children months after COVID, suggesting persistent infection can begin early in life.

long suspected and showed up in research before, but here's more proof this is a thing.

Nearly all people in the study were not vaccinated, and generally the sicker they were the more likely they had viral persistance.
