Clinical Characteristics and Outcomes of Long COVID-19 Hospitalized Children in Vietnam.

A cross-sectional study was conducted on 205 pediatric patients, including 150 post-COVID-19 patients and 55 noninfected patients. The study identified 10 common respiratory symptoms in post-COVID-19 patients, with significant differences in clinical symptoms between the 2 groups. Post-COVID-19 pediatric patients had a lower lymphocyte count and a higher rate of pneumonia diagnosis, which can persist for up to 16 weeks after discharge. The study's findings can help monitor and manage the clinical burden of post-COVID-19 symptoms in the pediatric population.
