Can kids be harmed wearing masks to protect against COVID? No, there is no scientific evidence showing masks cause harm to kids’ health despite baseless claims suggesting otherwise. Some argue that young children miss important visual and social cues that enhance learning and development when their classmates and teachers are wearing masks. There’s strong evidence masking children in schools can reduce COVID-19 transmission to other children and adults. To avoid skin irritation, doctors suggest washing masks regularly, making sure they fit properly and picking masks made with soft, breathable fabric.
