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. The findings, published in Frontiers in Immunology, help explain why long COVID often includes neurological symptoms such as brain fog, fatigue and mood changes, while influenza is more commonly associated with respiratory complications.

Long-COVID symptoms persist for years in nonhospitalized adults, study reveals Study of 130 non-hospitalised Long COVID adults in Sweden found that at 2.5 years ~50% had severe dyspnea and depression, and 42% had impaired lower-body strength on testing at clinic. www.cidrap.umn.edu/covid-19/lon...

"Study shows COVID-19 raises risk of 'vascular aging' with stiffer arteries." COVID-19 doesn’t only affect the lungs. New research shows people who’ve had COVID-19 have stiffer arteries than those never infected, highlighting ongoing cardiovascular risks after infection.

Study: COVID-19 raises risk of 'vascular aging' with stiffer arteries
When people think about COVID-19, they may think about how it affects their respiratory system. A new study shows how it can affect "vascular aging."

Vaccination didn't eliminate the increased danger posed by a 2nd infection compared to a 1st infection. The pattern was the same: Reinfection resulted in a higher risk of PASC for all children and adolescents Zero mitigation in schools #CleanAir4Kids www.thelancet.com/journals/lan...

If convincing people to get the measles vaccine is ‘slow going’ this calls for a vaccine-PLUS approach. Kids/Educators/Bus drivers have the right to NOT get infected, especially those at high risk. Vaccine-PLUS means: +masks +air filtration +ventilation +more! globalnews.ca/news/1117224...
