An ABC News analysis of COVID-19 trends in all 50 states, as well as Washington, DC and Puerto Rico, found that newly confirmed cases have increased in 28 states in the past two weeks.
The analysis also found an increase in the daily positivity rate of COVID-19 tests in 25 states, an increase in COVID-19 hospital stays in 35 states, and an increase in daily COVID-19 deaths in 18 states plus Puerto Rico.
The seven-day average of new cases in the US has now exceeded 44,000, the highest since August 21.
Two states – Montana and South Dakota – reported the highest increases in the number of new COVID-19 cases in a day. Seven states – Arkansas, Iowa, Montana, Oklahoma, South Dakota, Wisconsin, and Wyoming ̵
Although the numbers in the northeast are still relatively low, the number of new cases is slowly increasing compared to the numbers in the spring. The region’s 7-day mean for new cases is now the highest since June 2. In the last month alone, that average has risen by more than 69%.
In the Midwest, the number of new cases continues to reach a record level with an average of 13,200 cases per day, mainly due to the consistently high case numbers in Montana, North Dakota, South Dakota and Wisconsin. The number of current COVID-19 hospitalizations in many Midwestern states continues to rise as well. As of Sunday, current hospital stays in Montana, Nebraska, North Dakota, Oklahoma, South Dakota and Wisconsin have reached record highs.
The number of new cases in the south is still significantly lower than in summer. However, the south still accounts for more than 45% of the country’s daily regional case numbers, with an average of over 18,000 new cases per day.
In the past three weeks, the number of new cases in the west has increased by 26%. Idaho and Utah continue to produce high numbers of cases each day. Although the numbers in California are declining, the state continues to report large numbers of new cases every day.
The trends have all been analyzed using data collected and published by the COVID Tracking Project over the past two weeks, using the seven-day moving average linear regression trendline.
