Children have milder cases of COVID-19 due to their heightened exposure to other infections, boosting their immune responses. Researchers found that children have a more active innate immune system in their nasal passages compared to adults. They studied over 600 nasal swabs from pediatric patients and found that children with higher levels of respiratory pathogens showed higher levels of nasal immune activity. Children typically displayed higher innate immune activity during infections, suggesting their defenses are activated in response to respiratory viruses. Researchers believe that further study of respiratory viruses and bacteria could impact disease severity of COVID-19 and pediatric immune responses.
