We performed 2 surveys during 2022 to estimate point prevalences of SARS-CoV-2 infection compared with overall viral seroprevalence in Sweden. Point prevalence was 1.4% in March and 1.5% in September. Estimated seroprevalence was >80%, including among unvaccinated children. Continued SARS-CoV-2 surveillance is necessary for detecting emerging, possibly more pathogenic variants.
