The U.S. has reported more than 31.0 million confirmed COVID-19 cases as of Apr. 15, 2021. More than 550,000 Americans have died of COVID-19 — the highest death toll of any country.

The virus has spread throughout the country in a way that has been difficult to predict, surging in one region, then showing signs of improvement, and then reappearing in other regions. Though local outbreaks may ebb and flow, the current surge in cases has been felt nearly nationwide, leading to new travel restrictions and business closures around the country.

Nationwide, there were an average of 21.2 daily new coronavirus cases per 100,000 Americans in the week ending Apr. 15, 2021. Cumulatively, the U.S. has reported 9,484.3 cases per 100,000 Americans, and 170.6 deaths per 100,000 Americans.

The extent of the spread of the novel coronavirus continues to vary considerably from state to state, and even from county to county. Even as the number of daily new cases is flattening or even declining in some parts of the country, new cases are surging at a growing rate in others.

The coronavirus has spread to different parts of the country in different stages throughout the pandemic. In the spring, the worst hit states were in the Northeast, as New York City became the epicenter of the nation’s crisis. The virus spread to states throughout the Sun Belt in the summer, and hit states in the Midwest and West during the fall. Now, nearly every state is categorized as a COVID-19 hotspot, according to definitions based on new cases per capita from the nonprofit health organization Kaiser Family Foundation.

In Tennessee, there were an average of 16.9 daily new coronavirus cases per 100,000 residents in the week ending Apr. 15, 2021. The Tennessee case growth rate ranks as the 24th lowest of all 50 states.

While the nation’s largest counties were hit hardest in the early months of the pandemic, nearly every county has suffered from the coronavirus. Outbreaks can occur quickly in places where large numbers of people tend to congregate, leaving counties with colleges, correctional facilities, and nursing homes particularly at risk.

In Humphreys County, there were an average of 33.9 new confirmed cases per day per 100,000 residents in the week ending Apr. 15, 2021 — the highest rate of any county in Tennessee. Since the pandemic began, the county has reported 1,702 confirmed cases, or 9,291.4 cases per 100,000.

There have been 21 deaths, or 114.6 deaths per 100,000 residents.

To determine the county in each state with the highest rate of daily cases of the virus, 24/7 Wall St. compiled and reviewed data from state and local health departments. We ranked counties according to the average new number of cases per 100,000 residents per day during the week ending Apr. 15, 2021. Population data used to adjust case and death totals came from the U.S. Census Bureau’s 2018 American Community Survey and are five-year estimates.

These are all the counties in Tennessee where COVID-19 is slowing (and where it’s still getting worse).
