Abstract

Objective: To describe the epidemiological, clinical, and paraclinical characteristics of children with adenovirus pneumonia treated at the Nghe An Obstetrics and Pediatrics Hospital. Methods: This was a cross-sectional descriptive study included 118 children aged from 1 month to 15 years old diagnosed with adenovirus pneumonia at Nghe An Obstetrics and Pediatrics Hospital between July 2022 to June 2024. Results: The majority of cases occurred in children over 12 months old (61%), with a male-to-female ratio of 1.8:1. The disease occurred at anytime but most common in the winter and spring (October to March). Community transmission was the primary source of infection (76.3%). Clinical manifestations included cough (100%), fever (98.5%), runny nose (94.1%), and moist rales in both lungs (93.2%). The average duration of fever was 6.02 ± 3.08 days. Most patients had normal white blood cell counts (66.1%), and 80.5% exhibited elevated CRP levels. Chest X-ray showed diffuse interstitial infiltrates in both lungs (70.3%). Co-infection with other microorganisms was found in 22% of cases, with bacterial co-infections accounting for 11.8%, viral co-infections were 10.2% of cases. Conclusion: Adenovirus pneumonia is more common in children over 12 months old. The disease frequently occurs during the winter and spring. Clinical symptoms are specific for pneumonia. Most patients exhibited elevated CRP levels. Chest X-ray showed diffuse interstitial infiltrates in both lungs. Co-infection with microorganisms was found, including both bacteria and virus.
