Fig. 1

Circulating SARS-CoV-2 variants of concern (VOC) in Uppsala County, Sweden during 2021. (A) Shows the week-wise distribution of the number of confirmed COVID-19 cases in Uppsala County, Sweden (grey) and the number of positive samples that were subsequently sequenced (black). The number of confirmed cases (per week) was collected from the Swedish Public Health Agency’s official COVID-19 statistics (https://www.folkhalsomyndigheten.se/smittskydd-beredskap/utbrott/aktuella-utbrott/covid-19/statistik-och-analyser/bekraftade-fall-i-sverige/, accessed on the 25th of March 2022). (B) Shows the distribution of the SARS-CoV-2 VOC (or non-VOC) during 2021 (between week 15 and 52) from the COVID-19 positive samples that were sequenced in our laboratory. The distribution is displayed as percentage (%) of sequenced samples per week. VOC classifications: according to the pangolin lineage system and WHO’s definition of VOC (https://cov-lineages.org; https://www.who.int/en/activities/tracking-SARS-CoV-2-variants/).
