Objective
The implementation of nonpharmaceutical interventions (NPIs) for coronavirus disease 2019 (COVID-19) may affect the incidence of infectious diseases. This study aimed to evaluate the changes in the incidence of pediatric acute otitis media (AOM) after the COVID-19 outbreak in Seoul, South Korea.
Study Design
Retrospective cohort.
Setting
Tertiary referral center.
Patients
We ascertained the daily number of COVID-19 and pediatric AOM patients between January 20, 2020, and June 19, 2020. During the same period, the number of children using public transportation was used as an index for implementing NPIs. The same period 1 year ago was set as the control period.
Intervention
Diagnostic.
Main Outcome Measure
The differences in the incidence of AOM and implementation of NPIs between the COVID-19 pandemic and control period were analyzed using segmented regression analyses. Negative values of difference meant that the number in the COVID-19 pandemic period declined compared with the control period.
Results
The study period was divided into two sections based on the change point of the COVID-19 cases. In the first period, the increased number of COVID-19 cases decreased, and in the second period, the number of COVID-19 cases increased again. Similar trends were observed in the incidence of AOM and NPI implementation. Before the change point, the study found a significant decreasing trend in the differences in pediatric AOM cases and children using public transportation. However, these trends changed after the change point, with a significant increase in both indices.
Conclusion
Our findings indicate that NPIs for COVID-19 may influence the incidence of pediatric AOM.
