COVID-19: This Is America's Worst Hot Spot

The U.S. has reported more than 31.4 million confirmed COVID-19 cases as of Apr. 21, 2021. More than 560,000 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 20.8 daily new coronavirus cases per 100,000 Americans in the week ending Apr. 21, 2021. Cumulatively, the U.S. has reported 9,599.4 cases per 100,000 Americans, and 171.9 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 nation’s worst COVID-19 hot spot is in Georgia. In Chattahoochee County, there were an average of 149.7 daily new coronavirus cases per 100,000 Americans in the week ending Apr. 21, 2021 — more than seven times greater than the national case growth rate and the most of any county in the country.

Other national hot spots include Dimmit County, Texas; Crosby County, Texas; and Grant County, Oregon. Case growth in these counties range from 142.4 daily new cases per 100,000 residents to 136.9 daily new cases per 100,000.

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. 21, 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.
