Pediatric SARS-CoV-2 Seroprevalence, Oregon, USA, November 1, 2020–June 30, 2022
We estimated SARS-CoV-2 seroprevalence in children in Oregon, USA, at 6 time points. Seroprevalence increased linearly during November 2020–December 2021 and peaked in February 2022 at 38.8% (95% CI 32.8%–46.5%).

Cross-Canada Variability in Blood Donor SARS-CoV-2 Seroprevalence by Social Determinants of Health
We compared the seroprevalence of SARS-CoV-2 anti-nucleocapsid antibodies in blood donors across Canadian regions in 2021. The seroprevalence was the highest in Alberta and the Prairies, and it was so low in Atlantic Canada that few correlates were ...
