While most cases of COVID-19 in children are mild or even asymptomatic, there are certain situations where children have a higher probability of becoming infected. Some conditions that place certain children at risk for COVID-19 include obesity, diabetes, asthma and other chronic lung diseases, congenital heart disease, an impaired immune system (immunosuppression due to a medical condition or due to certain medications), neurodevelopmental disorders, sickle cell disease, chronic kidney disease, and other genetic or metabolic conditions.
