The imposition of mask mandates among school children during the pandemic did not affect the incidence of COVID-19 infection, according to research conducted in Finland.
The study, published in the journal BMC Public Health on April 21, was conducted in three Finnish cities—Helsinki, Turku, and Tampere. These cities had similar baseline incidences of COVID-19 between August and September 2021. At the time, the federal government had recommended using masks in schools for children aged 12 years and above. In Helsinki and Tampere, the national recommendation was imposed as mandates at schools while in Turku, the mandate was levied on kids aged 10 and above.
