(Stacker) — The vaccine deployment in December 2020 signaled a turning point in the COVID-19 pandemic. By the end of May 2021, 40% of the U.S. population was fully vaccinated. But as vaccination rates lagged over the summer, new surges of COVID-19 came, including Delta in the summer of 2021, and now the Omicron variant, which comprises the majority of cases in the U.S.

Researchers around the world have reported that Omicron is more transmissible than Delta, making breakthrough and repeat infections more likely.

The United States as of May 18 reached over 1 million COVID-19-related deaths and 83.4 million COVID-19 cases, according to Johns Hopkins University. Currently, 66.5% of the population is fully vaccinated, and 46.4% of vaccinated people have received booster doses.

Stacker compiled a list of the counties with highest COVID-19 infection rates in Oregon using data from the U.S. Department of Health & Human Services and vaccination data from Covid Act Now. Counties are ranked by the highest infection rate per 100,000 residents within the week leading up to May 17, 2022. Cumulative cases per 100,000 served as a tiebreaker.

Keep reading to see whether your county ranks among the highest COVID-19 infection rates in your state.
