Trends in seropositivity rates to SARS-CoV-2 were evaluated using Joinpoint within specific age groups and compared to educational institutions activity. Seropositivity rates increased significantly in the 0-<6 and 12-<16 years age groups and were parallel in the 0-<6 years age group and partially parallel in the 12-<16 years to educational institutions activities. Non-significant increase in seropositivity rates were observed in the age groups 6-<10 and 10-<12 years. Apparently, exposure to SARS-CoV-2 in children was driven not only by educational activities but also by other factors.}, issn = {2375-1924}, doi = {10.18103/mra.v10i3.2706}, url = {https://esmed.org/MRA/mra/article/view/2706} }
