I had 7+ covid, more likely 10. All mild and no long covid, although I get sick easily now. It's been a year finally covid free and my brain fog is still intense. Can't form sentences as easily as before. Probably lost 10 IQ points.

February 2024 study in the New England Journal of Medicine that shows that every infection impacts the brain - Very large study that followed 800,000 people over three years. Link to study: https://www.nejm.org/doi/full/10.1056/NEJMoa2311330

What Repeat COVID Infections Do to Your Body, According to Science SARS-CoV-2 behaves differently than a common cold or flu virus—and can do major long-term damage. https://www.self.com/story/covid-reinfection-health-effects

Memorial Sloan Kettering: One of the most concerning long-term impacts of COVID-19 is immune dysregulation and dysfunction. https://libguides.mskcc.org/CovidImpacts/Immune

New research shows COVID’s impact is more prolonged than previously thought, with signs of inflammation and traces of virus detectable years after infection. The results raise uncomfortable questions about long-term health implications that we are only beginning to understand. https://www.statnews.com/2024/07/03/long-covid-ucsf-study-finds-virus-presence-years-post-infection/
