BACKGROUND: To compare the differences in child development between children who contracted COVID-19 after February 1st, 2022, the period when the B.1.1.529 variant outbreak began to peak in Thailand, and those who did not.
METHODS: A prospective cohort study was conducted in an outpatient pediatric clinic at a tertiary hospital in southern Thailand. COVID-19 was diagnosed based on the results of an FDA-approved antigen test or RT-PCR using a swab sample collected from the nasopharynx, nose, or throat. Child development was assessed using the Ages and Stages Questionnaire, Third Edition (ASQ-3).
RESULTS: Of the 336 participants, 180 (53.6%) had a history of COVID-19. Almost all of them had mild COVID-19. The mean (SD) age at infection was 1.3 (0.3) years, and the median (IQR) duration between infection and ASQ-3 assessment was 193.5 (167.8, 216.2) days. The ASQ-3 scores at the ages of 18 (n = 166; 90 COVID-19 positive) and 24 months (n = 170; 90 COVID-19 positive) revealed no statistically significant differences between children with and without a history of COVID-19. Both groups had comparable proportions of developmental scores <1 SD below the mean.
CONCLUSIONS: Mild COVID-19 in young children did not increase the risk of developmental delays.
IMPACT: This cohort study was conducted during the Omicron pandemic. Of the 336 children, no clinical or statistically significant differences were observed in the scores of the Ages & Stages Questionnaire, Third Edition, at 18 or 24 months of age among the 180 participants with a history of mild SARS-CoV-2 infection, at an average of 6 months post-infection, and those without. The findings suggest that mild SARS-CoV-2 infection before the age of 2 years is not associated with developmental delays. Strategies to prevent severe SARS-CoV-2 infection in young children, especially COVID-19 immunization, need to be highlighted.
