While most children with COVID-19 experience mild symptoms or have no symptoms at all, some can become severely ill. Ziqitza says like adults, children can also spread the virus to others even if they are asymptomatic. Babies under 1 year old, and children with certain underlying conditions, may be more likely to experience severe illness if they contract COVID-19. Experts are also investigating the risk of a rare condition called Multisystem Inflammatory Syndrome in Children (MIS-C) which is associated with COVID-19 in children.
