An additional 3,245 cases of COVID-19 have been reported in Wisconsin since July 21, more than double the number of new cases reported in the week prior, the Wisconsin Department of Health Services reported Wednesday, July 28.

The rise in the number of new cases prompted DHS to adopt new Centers for Disease Control and Prevention guidance recommending fully-vaccinated people in indoor settings wear a mask in areas with high rates of infection. Nine counties in northwest Wisconsin have high rates of infection. Only Douglas County has a medium level of new infections, DHS data shows.

“Wisconsin’s seven-day average for new confirmed and probable cases has been trending upward,” said DHS Deputy Secretary Julie Willems Van Dijk. “We are concerned with this trajectory, along with the increasing proportion of sequenced SARS-CoV-2 specimens that are the delta variant.”

On Wednesday, the seven-day average was 478, more than double what the 221 reported July 21. The seven-day average of positive cases measures the average number of new cases per day over the previous week. An increase in the seven-day average of positive cases indicates the number of confirmed COVID-19 infections in the state is going up, according to DHS.

Between Jan. 1 and July 22, over 98% of COVID-19 cases in Wisconsin occurred among people who were not fully vaccinated, according to DHS.

The state's total number of COVID-19 cases was 619,040 Wednesday. An additional 68 Northwestern Wisconsin residents tested positive for COVID-19 over last week, DHS reported.

They were reported as follows: 12 in Bayfield County; 11 in Sawyer County; 10 in each Burnett and Taylor counties; six in each Iron and Washburn counties; five in Douglas County; four in Rusk County; three in Ashland County; and one in Price County.

An additional 43 deaths were recorded statewide since July 21, bringing the total to 7,433 on Wednesday, DHS said. Only three of those deaths, including one person in Price County, was reported for the first time in the last week, DHS data showed. One person in Burnett County who died prior to June 20 was also included in the deaths reported Wednesday.

The number of negative tests in the state was 3,023,033 Wednesday, an increase of 16,405 since July 21.

An additional 328 people were listed as hospitalized because of the virus, bringing the total to 34,888. Only 85 of those hospitalizations were reported for the first time since July 21, according to DHS. As public health officials continue to improve data quality, the remaining hospitalizations were first reported prior to July 21. The seven-day average Wednesday was 171 people hospitalized with 49 being treated in intensive care.

DHS also reports that 5,801,408 doses of vaccine have been administered by Wednesday. That means a total of 3,008,956 Wisconsin residents have received at least one dose of vaccine, and 2,864,148 people, 49.2% of the population, have completed the vaccine series.
