Kuitunen I, Artama M, Mäkelä L, et al. - Using hospital patient information systems and the Finnish national infectious disease register, researchers conducted this register-based study to evaluate the immediate impacts of national lockdown orders due to coronavirus disease 2019 (COVID-19) on the pediatric emergency room (ER) visits and respiratory tract infections in hospitals and nationwide in Finland. The sample consisted of all patients attending pediatric ER in 2 Finnish hospitals (Kuopio University Hospital, Mikkeli Central Hospital) covering 1/5th of the Finnish children population, 4 weeks before and 4 weeks after the start of the nationwide lockdown on March 16, 2020. During the nationwide lockdown relative to the study period before the lockdown, a major decrease in the rate of daily median pediatric ER visits was found in both hospitals in the study. Throughout the study period, no pediatric cases of COVID-19 were found at participating hospitals. Such findings strongly suggest that social distancing and other lockdown strategies are successful in preventing the spread of common respiratory viral diseases and reducing the need for children to be hospitalized.
