ALPENA — As of Thursday, at least 943 Northeast Michiganders were actively infected with COVID-19, while about 60% of Northeast Michiganders 5 and older had been fully vaccinated against the disease.

This week’s active infections — a News estimate based on cumulative infections minus deaths and those who fit the U.S. Centers for Disease Control and Prevention’s definition of recovered — is down from 1,029 active infections last week.

The number of active infections is likely higher, as The News’ estimate is based on numbers reported through District Health Departments No. 2 and No. 4 and doesn’t account for any positive results from home testing not reported to the health departments. It also doesn’t account for asymptomatic people who never take a test but could still spread the disease.

Meanwhile, among those 5 and older, the state says 57% of Alpena County residents, 65% of Presque Isle County residents, 62% of Montmorency County residents, and 57% of Alcona County residents have been fully vaccinated against the coronavirus.

The state does not explain unexpected jumps in vaccination rates for Presque Isle and Montmorency counties and a decreased vaccination rate in Alcona County since last week.

Public health experts have said we could consider the coronavirus pandemic over once 70% of the population has been vaccinated.

In the past week, public health officials have reported 191 newly infected or probably infected Northeast Michiganders and the deaths of two Northeast Michiganders who had been infected with COVID-19.

Since February 2021, Northeast Michigan health officials have reported confirmed and probable infections as one number. A person counts as a probable infection if they’d been exposed to a confirmed infected person and are showing symptoms but hadn’t been tested, themselves — such as family members of infected people.

As of Monday, eight COVID-19 patients were admitted at MyMichigan Medical Center Alpena, one of them in intensive care. The hospital was 100% full. State officials watch hospital occupancy rates closely to decide whether to impose new restrictions meant to slow the spread of infection.

The state counts all beds licensed for use in its occupancy figures, but hospitals determine occupancy rates based on how many beds they can legally and safely fill with the staffing they have.

Since the pandemic’s start in mid-March 2020, public health officials have reported 10,756 Northeast Michiganders infected or probably infected, and 264 related deaths.
