RSV, Flu And COVID-19: How 3 Viruses Are Affecting Michigan

MICHIGAN — As Michigan families gather for the holidays, they may come home with more than warm memories as Americans are being sickened by three viruses — seasonal flu, respiratory syncytial virus, or RSV, and COVID-19.

RSV detections declined nationally during the week ending Saturday, after sharp rises since mid-October, according to the Centers for Disease Control and Prevention. At the same time, seasonal influenza cases are ticking up in all but a handful of states, and COVID-19 cases, hospitalizations and deaths are all trending upward as well.

Michigan reported 8,993 new COVID-19 cases on Tuesday, making for a seven-day average of 1,262, according to health officials, who also reported 275 COVID-19 deaths during that time, an increase from 123 the prior week.

Michigan is one of few states in the nation that is seeing minimal flu activity, according to the CDC. Fewer people are getting vaccinated against the flu, however, as health officials reported 2,262,178 doses administered, significantly less at this time than the past three years, state health officials said.

The Midwest region is starting to see RSV cases decline after seeing cases spike in October, according to the CDC. The number of positive RSV cases has seen a steady decrease to 12.594 from a peak of 25.379 on Oct. 29, according to PCR detection rates from the CDC.

However, children’s hospitals across the country are still seeing a surge of sick kids.

In Michigan, pediatric bed occupancy was running at 75 percent as of Thursday, according to an NBC News analysis of Department of Health and Human Services data. The tracker is updated daily at 1 p.m. EST, according to NBC.

Nationally, the most overwhelmed states are Idaho at 104 percent, Arizona at 98 percent, Utah at 97 percent, Nevada at 96 percent, Rhode Island at 93 percent and Kentucky at 91 percent.

Overall, U.S. hospitals beds are at about 83 percent capacity, with 7.5 percent used by COVID-19 patients, according to HHS data. In Michigan, 71 percent of hospital beds are occupied with 5 percent used by COVID-19 patients, according to state health officials.

No Health Emergency Yet

Last month, pediatricians asked the Biden administration to declare a public health emergency that would give hospitals and providers more flexibility to care for children.

In their joint letter to President Joe Biden and Health and Human Services Secretary Xavier Becerra, the Children's Hospital Association and American Academy of Pediatrics said “significant capacity issues in pediatric hospitals and communities require flexibilities that can only be provided through a formal emergency declaration.

The flexibilities were provided to care providers at the height of the coronavirus pandemic, and “children’s providers require the same capacity support as they strive to keep up with increasing needs of infants, children and adolescents.”

As of Thursday, the Department of Health and Human Services had not declared the health emergency. It would allow for the waiver of certain Medicare, Medicaid or Children’s Health Insurance Program requirements that would allow hospitals, physicians, and other health care providers to share resources and access emergency funding to keep up with the growing demands, specifically related to workforce support.

The reason for the so-called “tripledemic” threat? Months of hunkering down and avoiding contact with others during the COVID-19 pandemic weakened Americans’ immune systems, according to health experts.

“Public health officials have been bracing for this possibility since early in the pandemic,” Dr. Michael Mina, chief science officer at eMed and one of the nation’s leading epidemiologists, said in a statement to CBS MoneyWatch.

“The recent surges are fully expected ramifications of a new virus that caused massive swings in human behavior,” Mina said. “We know that immunity is working exactly as it was supposed to, and in this case, it means that we drained population-level immunity by not having exposures.”

Most children get an RSV infection by the time they’re 2, but people can be infected at any age and more than once in a lifetime, according to the CDC. The symptoms are typically similar to the common cold. But for the extremely young whose lungs aren’t fully developed, the very old and people whose immune systems are compromised, RSV can lead to breathing difficulties.

“Right now, the problem really is just the volume of sick children, Dr. Thomas Murray, a pediatric infectious diseases physician at Yale Medicine, said in a news release, “but we know how to help them.”
