In the past week, five states have accounted for about 44% of new Covid-19 cases, according to data from Johns Hopkins University.
New York, Michigan, Florida, Pennsylvania and New Jersey reported nearly 198,000 new Covid-19 cases over the past seven days. There were about 453,000 new cases in the country.
But those five states are home to just 22% of the US population, according to estimates from the US Census Bureau.
Michigan had the highest per capita case rate over the past week, with about 471 new cases reported per 100,000 residents, followed by New Jersey with about 335 new cases reported per 100,000 residents. Nationwide, there were about 137 new cases per 100,000 people reported over the past seven days.
