Michigan’s seven-day average for new COVID-19 cases has reached its highest point in eight weeks as the BA.5 omicron subvariant continues its spread.
On Tuesday, July 26, state health officials announced a seven-day total of 19,653 new confirmed and probable COVID cases, and 137 new confirmed and probable deaths.
The additions bring the state’s averages to 2,369 new cases and 13 new deaths per day over the last week. The case count is up nearly 19% from a week ago, and marks the highest average since late May.
Meanwhile, the daily average for COVID deaths dipped for the second consecutive week.
MDHHS has included both probable and confirmed cases in its totals since April 6. (A case is confirmed only when there is a positive PCR test. Cases are classified probable when there was no such tests but a doctor and/or an antigen test labeled them COVID.)
In total, there have been more than 2.67 million confirmed and probable cases, and 37,428 confirmed and probable deaths since the start of the pandemic in Michigan. Of them, 2,318,307 cases and 34,250 deaths are confirmed. About 354,005 cases and 3,178 deaths are probable.
Health officials acknowledge case counts are likely underestimates due to the transition to more at-home testing. By leaning more heavily on over-the-counter tests, residents are less likely to report their results to the local health department.

The chart below shows new cases for the past 30 days by county based on onset of symptoms. In this chart, numbers for the most recent days are incomplete because of the lag time between people getting sick and getting a confirmed coronavirus test result, which can take up to a week or more.

As of Tuesday, there were 942 adult and 33 pediatric patients with confirmed or suspected cases of COVID-19 being treated across Michigan’s hospitals. That’s up from 882 adults and 22 pediatrics a week ago.
Among the hospitalized patients Tuesday, 98 were receiving intensive care and 33 were on ventilators — both declines from last week.
Health systems are nowhere near the height of the omicron surge, which saw about 5,000 patients in the hospital as of Jan. 10. Among those patients, 860 were in the ICU and 540 on ventilators.
Health officials closely monitor deaths as an assessment of the severity of coronavirus transmission. Deaths have stayed at or below 20 per day since late March.
Thirty-seven counties reported at least one new death in the last seven days, led by Wayne with 19 and Oakland with 15. Other leading counties included Macomb with eight, Calhoun, Jackson and Eaton with four each, and Kent and Berrien with three deaths each.
