Seniors prime target of weaker COVID-19 wave in Minnesota

Death and severe illness rates have fallen among younger adults, leaving seniors once again with a disproportionate COVID-19 burden.

When COVID-19 finally found its way to Worketu Gigesa — after two years of her family protecting her — the infection hit her hard.

The 97-year-old was admitted to Abbott Northwestern Hospital in Minneapolis this week, despite the circulating strains of coronavirus appearing to cause less severe illness than earlier versions in the pandemic.

"She didn't want to eat, she didn't want to drink, and she got weak," said her daughter, Demitu Abdissa. "I didn't know what was going on and I got worried and called 911." Gigesa's experience reflects a statistical reality, even as the current COVID-19 wave shows signs of receding or leveling off in Minnesota ahead of a predicted milder summer. Whatever COVID-19 risk remains this spring, it has largely shifted back to seniors.

More than 90% of the COVID-19 deaths identified so far in May in Minnesota have been in people 65 and older — above the 66% among that population in December, when delta and earlier omicron variants took an elevated toll on younger, unvaccinated adults. The last time more than 90% of the state's pandemic deaths involved seniors was December 2020, before vaccine was widely available.

COVID-19 deaths have declined across all age groups in Minnesota since the start of 2022 — just more rapidly among younger adults. Provisional federal data showed a decline in COVID-19 deaths among nonelderly adults in Minnesota from 385 in December to seven so far in May. The comparable decline in senior deaths was 755 to 89. The declines reflect strong levels of immunity, vaccinations and antiviral drugs to combat the pandemic, but people still need to protect others around them who are vulnerable, said Dr. Ruth Lynfield, state epidemiologist and medical director of the Minnesota Department of Health.

"You need to know your exposure history. Have you been infected recently? Have you been vaccinated and boosted?" she said. "Certainly throwing on a mask should be like carrying an umbrella. It shouldn't be a big deal and, if you're going to interact with someone who is very fragile, absolutely you want to do whatever you can to protect that person."

COVID-19 hospitalizations in Minnesota have increased from a recent low of 183 on April 10 to 446 on Thursday, but many have been incidental — meaning the patients were admitted for other reasons and tested positive upon routine screening. The number of patients requiring intensive care has increased over the past week, but still represents only 10% of the total COVID-19 hospitalizations. That rate reached 30% at other severe points in the pandemic. Patients admitted for COVID-19 this spring are more likely to be seniors than they were during this winter's severe pandemic waves, said Dr. Mark Sannes, an infectious disease specialist for HealthPartners, which includes Regions Hospital in St. Paul and Methodist Hospital in St. Louis Park. However, these patients tend to also have other health conditions and symptoms. "Is that COVID, or is that something else?" he said. "That is kind of the nuanced presentation that I think we are seeing in that older population right now."

Seniors still vulnerable

Gigesa lives with her daughter and son-in-law at their home in Minneapolis. Abdissa, a food service worker at the Minneapolis-St. Paul Airport, said she took the threat of COVID-19 seriously when the pandemic emerged.

"I just used a mask and cleaned all the time to protect her," she said.

Abdissa said she hasn't ever tested positive herself and isn't sure how her mother got infected — twice this year. The first infection in January was worse, but the second one in May was frightening because it came so quickly — and after COVID-19 vaccinations and two booster shots.

The vaccine likely helped, though, the daughter said: "That's why she is alive, I think." The spread of the coronavirus appears much wider than is reflected in Minnesota's confirmed case counts, which include only publicly reported test results and not popular at-home rapid tests. The virus, as a result, has found its way back to vulnerable seniors and into nursing homes and other congregate-care facilities.
