Counties with highest COVID-19 infection rates in Idaho

As has been true throughout America’s COVID-19 history, every state—and every county therein—has its own COVID-19 story, driven by local policies and behaviors. The United States as of Sep. 14 had reached662,778 COVID-19-related deaths and 41.2 million COVID-19 cases, according to Johns Hopkins University. As of Feb. 2, more Americans had been vaccinated for COVID-19 than had been infected. But as vaccination rates lagged over the summer, new surges of COVID-19 came. More than 80% of these cases by late July were caused by the Delta variant, which is more contagious than the original virus. This has resulted in growing rates of community transmission and—especially in counties with lower vaccination rates—increasing rates of hospitalization and death.

Stacker compiled a list of the counties with highest COVID-19 infection rates in Idaho using data from the U.S. Department of Health & Human Services. Counties are ranked by the highest infection rate per 100k residents within the past week as of Sep. 13, 2021. Cumulative cases per 100k served as a tiebreaker Keep reading to see whether your county ranks among the highest COVID-19 infection rates in your state.
