MOUNT CLEMENS, Mich. (AP) — A sampling of sanitary sewage in one southeastern Michigan county has shown an increase in the presence of COVID-19.
Sewage samples pulled from sites across Clinton Township show the rate of actual infection is higher than numbers currently reported by state health officials, the Macomb County Public Works office said Tuesday.READ MORE: Detroit Police Department Holds Graduation Ceremony For Recruit Class 2021-G
Positive virus tests for Macomb County residents have increased 125% over the past 14 days, the office added.
Macomb County has reported more than 60,000 virus cases and 1,880 deaths since the start of the pandemic.
The state’s COVID-19 cases also have been increasing. Dr. Joneigh Khaldun, Michigan’s chief medical executive, has said Michigan’s case rate spiked 77% over the past four weeks to 172.9 cases per million people.READ MORE: Here's A Look At Weekend Construction Happening In Metro Detroit
As of Monday, Michigan had nearly 630,000 cases and more than 15,900 deaths.
“Testing shows the trend line of what’s coming about a week before,” Macomb Public Works Commissioner Candice Miller said. “Unfortunately, our testing is showing that COVID cases will continue to climb into next week.”
Laboratory testing of sewage to detect the coronavirus is considered more accurate in determining overall community infection because it includes sampling of waste shed by individuals who are already infected but who haven’t been tested, Miller’s office said.
The pilot project started in June, just north and northeast of Detroit. Its goal is to provide information to the county health department so officials can better target contact tracing or other actions they may be able to take to reduce the community risk, Miller said last year.MORE NEWS: FDA Approves Longer Shelf Life For J&J COVID-19 Vaccine
