Assessment on the incidence of notifiable infectious diseases in pediatrics post-COVID-19: a retrospective study based on data from 2020 to 2023

These findings establish a significant association between the relaxation of COVID-19 restrictions and increased pediatric infectious disease occurrence. In 2023, there has been a substantial increase in the number of pediatric outpatient and emergency department visits, as well as in the incidence rate of notifiable infectious diseases, when compared to the period from 2020 to 2022. Notably, the incidence of influenza has exhibited the most pronounced increase, while the incidence rates of measles and mumps have remained stable.
