Childhood Sleep Apnea Linked to Higher Viral Infection Risk

Children diagnosed with obstructive sleep apnea (OSA) are more likely to contract influenza and COVID-19, a major U.S. study indicates. The research, which analyzed electronic health records over five years, found a substantial rise in viral infection diagnoses among youngsters with OSA.

The study, involving over half a million children aged 2-18, compared those with OSA to matched controls. Results showed a nearly 80% higher risk of influenza diagnosis and more than double the risk for COVID-19 in children with OSA.

Even after common surgical interventions like adenotonsillectomy, the increased susceptibility to viral infections persisted. This suggests a deeper immune system impact beyond airway obstruction alone. The findings also noted a higher risk of pneumonia in OSA patients who contracted influenza or COVID-19.

These immune consequences add a critical layer to understanding the broad health implications of pediatric obstructive sleep apnea.
