Yet again We were right from the beginning when we said it was systemic!
Scientists found COVID-19 in the brain months after infection.
The study, led by NIH scientists, analyzed tissue from 44 people who died with COVID-19 in the first year of the pandemic. To their surprise, SARS-CoV-2 was detected in multiple parts of the body â including the brain â and in some cases, it was still active.
In one individual, scientists were even able to culture live, replication-capable virus from brain tissue, suggesting it hadnât just left fragments behind; it was still viable.
Researchers used freshly dissected brain samples and tested 10 different regions. Viral RNA and proteins were found in most of them. But the brain showed little to no inflammation or direct damage, raising big questions: is the virus causing neurological symptoms, or is it just quietly lingering?
This may help explain why some people with COVID, or Long COVID, experience confusion, memory problems, headaches, or even more severe neurological complications â though the link is still unclear.
Not everyone in the study had these symptoms. And all subjects were unvaccinated, with severe COVID. But the findings confirm something critical: SARS-CoV-2 doesnât always stay in the lungs.
It may travel through the body, persist for months, and hide in tissues that don't show classic signs of infection.
We still donât fully understand how or why COVID affects the brain. But studies like this push us one step closer.
