New cases of COVID-19 in the United States fell for a third week in a row, dropping 15% last week to 347,000, the lowest weekly total since October, according to a Reuters analysis of state and county data.
Nearly a third of the country’s population has been fully vaccinated as of Sunday, and 44% has received at least one dose of a COVID-19 vaccine, according to the U.S. Centers for Disease Control and Prevention.
Michigan again led the states in new cases per capita, though new infections fell 26% last week compared with the previous seven days, the Reuters analysis showed. New cases also fell in Colorado and Minnesota, the states with the next highest rates of infection based on population.
Health officials have warned that more contagious variants of the coronavirus are still circulating, such as the B.1.1.7 variant first detected in the United Kingdom and partly responsible for the surge in Michigan.
In Oregon, where the B.1.1.7 variant is now the dominant strain, the governor last week placed nearly half the state’s counties in the extreme risk category for COVID-19, banning indoor dining and restricting capacity at other businesses.
Oregon reported a 1.2% rise in new cases last week to about 5,600, double the weekly cases seen in early April.
Nationally, deaths from COVID-19 fell 3% to 4,819 in the week ended May 2, the fewest deaths in a week since July.
The average number of COVID-19 patients in hospitals fell 8%, the first weekly decrease after rising or holding steady for four weeks.
Vaccinations fell for a second week in a row, dropping 12% after falling 14% in the previous week.
As of July 27, reports of COVID-19 cases and deaths are sourced to Reuters reporting in order to streamline data reconciliation efforts when discrepancies arise. Testing data continues to come from The COVID Tracking Project.
About the data: On March 1, 2021, this page stopped using new hospitalization and testing data from The COVID Tracking Project in anticipation of that project’s end. The hospitalization data shown here was collected by Reuters after August 1, 2020. The previous data comes from The COVID Tracking Project’s archives.
The vaccination data comes from the Centers for Disease Control and Prevention.
Reuters collates and checks this data by hand and the figures largely come from state, county and territory government/public health department websites. Reuters also occasionally sources information from press conferences, press releases and verified tweets and social media posts by state officials. While some states and counties report fresh numbers daily, others only update on weekdays or less frequently.
Reuters’ total cases and deaths include both confirmed and probable cases and deaths where data is available. If probable cases and deaths are not reported, only confirmed cases and deaths are shown.
On April 7, 2021, Oklahoma reported 1,716 new deaths that occurred between August and February that had gone unreported due to an error by a lab.
A change in reporting methodology in Iowa on Feb. 19 resulted in a one-time increase of over 27,000 new cases.
A spike observed in deaths in Ohio and nationally in early February 2021 is due to Ohio including 4,275 probable deaths from earlier in the pandemic.
A spike observed in deaths in Indiana and nationally in early February 2021 is due to Indiana including over 1,500 probable deaths from earlier in the pandemic.
Missouri cases and deaths for the week ended Jan. 31 include a one-time increase due to Reuters including data reported by St. Louis County.
Texas began reporting probable cases on Dec. 11. The change resulted in a one-day increase of roughly 65,000 cases.
On Sept. 2, Massachusetts adopted a more restrictive definition for probable cases, which resulted in a significant fall in the number of cases. Reuters has reconciled all historical data to reflect this change in methodology
Virginia reported a large backlog of positive infections on Aug. 7, resulting in an abnormal spike in cases.
On July 30, Minnesota began reporting the total number of people tested instead of total specimens tested. This changed the state total by more than 173,000 tests for July 31.
A spike observed in deaths in New Jersey and nationally in late June is due to New Jersey including over 1,800 probable deaths from earlier in the pandemic.
Wyoming’s spike in late April is due to the inclusion of probable cases.
New cases in Alabama more than doubled to 7,787 in late March but this included a backlog.
