The acceleration in the spread of COVID-19 in the United States in the past month is nothing short of astonishing. Confirmed cases now routinely rise by over 150,000 a day, on the way to what experts think will be 250,000. Fatal cases per day have risen to 2,000, and experts fear that could double. Currently, total confirmed cases in the United States stand at 15,038,546 and fatalities at 286,692.

Some parts of the country are much worse off than others. The states in the upper Midwest are now taking the brunt of the disease. This includes Montana, Wyoming, North Dakota, South Dakota, Minnesota and Iowa. Case counts in states where the growth slowed earlier in the year also have picked up. This includes, in particular, New York, which was hit worse than any other state in terms of deaths during a horrible period from late March through April. The state still has more fatal cases than any other.

The effects of the disease on any area are measured in several ways. Among the most widely followed are cases per 100,000 people. This shows how deeply COVID-19 has spread in any given county. It also can be a sign of likely future spread because such a large portion of the population already has been affected.

Until vaccines can slow and eventually start to eliminate COVID-19, people have to be on guard for the spread of the disease in their own communities. 24/7 Wall St. has looked at each state to determine the counties where the cases per 100,000 are the highest. We also have shown a more grim figure, which is deaths per 100,000.

The ways that people can protect themselves regardless of the intensity of the spread of the disease have changed very little since the start of the pandemic. Wear masks, social distance, wash hands and, when talking, stay outside as much as possible. Just as important, do not gather inside in groups of more than a few people.

This list shows the five counties in each state where the cases per 100,000 are the highest. It provides a picture of which areas in a state are most dangerous in terms of the spread of the disease.
