Research associates prior encounter with seasonal coronavirus to milder COVID-19 symptoms
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.
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 people are likely to develop the most severe symptoms of COVID-19.
