The document discusses COVID-19 and provides information on diagnosing, transmission of, and effects on children. COVID-19 is a disease caused by a new coronavirus (SARS-CoV-2) that spreads mainly person to person via respiratory droplets from infected individuals. Diagnosis involves testing nasal or throat swabs or saliva for the virus. While anyone can be infected, children generally experience milder symptoms than adults but can still spread the virus. The elderly and those with chronic conditions are at higher risk of severe COVID-19.
