COVID-19 in Pediatrics: A Diagnostic Challenge.

Most pediatric patients with COVID-19 described in the literature have unusual or mild respiratory symptoms. Fever is usually a prominent feature. Cough is described frequently. Less common are sore throat, headache, productive cough, nausea, and diarrhea. Some studies estimate that children made up about 2% of the affected population. Nearly 1.2% of infected children need hospital treatment and some children require mechanical ventilation. The immune system in children is in its development stage, therefore the immune response to pathogens is different from adults.
