Stanford study ties milder COVID-19 symptoms to prior run-ins with other coronaviruses
In COVID-19 patients whose symptoms were mild, Stanford researchers found that they were more likely than sicker patients to have signs of prior infection by similar, less virulent coronaviruses, Stanford University stated in a press release.
A study by Stanford University School of Medicine investigators hints that people with COVID-19 may experience milder symptoms if certain cells of their immune systems “remember” previous encounters with seasonal coronaviruses — the ones that cause about a quarter of the common colds kids get.
Immune cells that are better equipped
These immune cells are better equipped to mobilize quickly against SARS-CoV-2, the coronavirus responsible for COVID-19, if they’ve already met its gentler cousins, the scientists concluded.
The findings may help explain why some people, particularly children, seem much more resilient than others to infection by SARS-CoV-2, the coronavirus that causes COVID-19. They also might make it possible to predict which pe ...
