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 investigating the immediate effects of national lockdown orders due to coronavirus disease 2019 (COVID-19) on pediatric emergency room (ER) visits and respiratory tract infections in hospitals and nationwide in Finland. All patients visiting pediatric ER in 2 Finnish hospitals (Kuopio University Hospital, Mikkeli Central Hospital) 4 weeks before and 4 weeks after the start of the nationwide lockdown on March 16, 2020, were included as participants, which covers 1/5th of the Finnish children population. Both hospitals in the study showed a major reduction in the rate of daily median pediatric ER visits during the nationwide lockdown compared with the study period before the lockdown. Findings strongly suggest effectiveness of social distancing and other lockdown strategies in slowing down the spreading of common respiratory viral diseases and reducing the necessity for hospitalization among children.
