Abstract
Background
To date, coronavirus disease-2019 (COVID-19) has infected over 82 million people globally. The first confirmed case in the United Arab Emirates (UAE)was reported on 29th January 2020. Current data suggests that children with COVID-19 have a mild disease course. There is a lack of extensive published data about COVID-19 infection among children in the Arabian Gulf region.
Methods
This cross-sectional multicenter study included children with confirmed COVID-19 infection admitted between March 1st and June 15th, 2020 to three large hospitals in Dubai, UAE. Serial nasal swabs for COVID-19 polymerase chain reaction (PCR) testing were collected during hospitalization. We investigated patients’ demographics,clinical characteristics, radiological and laboratory investigations during their inpatient hospital course.
Results
111 children were included in our study and represented 22 nationalities. Fifty-nine (53.2%) were boys. The mean age was 7 years (±5.3), and 15.3% of children were younger than 1 year. Only 4 (3.6%) children had pre-existing asthma, all of whom had an uneventful clinical course. At presentation 43 (38.7%) were asymptomatic, 68 (61.2%) had mild or moderate symptoms and none had severe illness requiring intensive care. Fever (20.7%), cough (19.8%) and rhinorrhea (15.3%) were the most common presenting symptoms, most of which resolved by day 5 of hospitalization. Most of our patients had a normal chest x-ray. The most common laboratory abnormalities on admission included variations in neutrophil count (24.7%), aspartate transaminase (22.5%), alkaline phosphatase (36.7%) and lactate dehydrogenase (42.5%). Children were infrequently prescribed targeted medications, with only 4 (3.6%) receiving antibiotics. None of the 52 patients tested for viral co-infections were positive. COVID-19 PCR turned negative at a median of 10 days [6–14 days] after the first positive test. Overall, there was no significant difference in time to negative PCR between symptomatic and asymptomatic children.
Conclusion
This pediatric study of COVID-19 presents a first look into the burden of COVID-19 infection among children in the UAE. Patients had various laboratory abnormalities despite clinical stability. We conclude that a large percentage of children with COVID-19 infection experience no symptoms, and severe disease is uncommon in the UAE. Ongoing surveillance, contact tracing and public health measures will be essential in containing future outbreaks.
