Long-term brain effects of COVID-19 vs. flu: Study reveals key differences

Even a mild case of COVID-19 or the flu can impact the body long after the fever and cough fade, according to new Tulane University research that may help explain why some people struggle to feel fully recovered weeks or months later. Tulane researchers found that while both viruses can leave lasting lung damage, only SARS-CoV-2 infection caused persistent brain inflammation and small blood vessel injury, even after the virus was no longer detectable.
