Grand Rapids children’s hospital limits visitors amid rise in respiratory illnesses



Helen DeVos Children’s Hospital is limiting the number of visitors in its pediatric areas due to health concerns amid rising respiratory illnesses.

Effective immediately, only two people are permitted at the bedside of patients during the day and one person overnight, according to the new temporary guidelines issued by Corewell Health Thursday, Jan. 30.

Hospital officials said the change was due to a “high number of pediatric admissions and an increase in respiratory illnesses throughout the community.”

The new restrictions only apply to pediatric inpatient units, which are open and ready to care for patients, the hospital said. There may be longer wait times or beds in non-traditional settings because of the increased number of patients.

Michigan flu cases surge; some kids on ventilators, health officials say
January 8, 2026

Flu cases are surging in Michigan, state health experts say, as the flu season has hit harder and earlier than when it typically does, say some.

The Michigan Department of Health and Human Services has recorded 2,110 influenza-related hospitalizations this flu season, including 306 among children ages 4 and under. The disease is responsible for "at least" eight U.S. pediatric deaths this season, said Dr. Natasha Bagdasarian, the state's chief medical executive.

The surge has impacted the state's youngest residents, some who have needed ventilators to help them breathe.

"We're hearing from (pediatric hospitals and other facilities that treat children) those influenza cases are increasing exponentially," said Bagdasarian on Wednesday during a virtual media roundtable with other experts. "They're also seeing a massive influx of influenza cases in their ICUs and on ventilators. Again, these are pediatric cases."

Ryan Malosh, director of the Division of Immunization at the Michigan Department of Health and Human Services, said Michigan is seeing a 40% increase in hospitalizations due to flu compared to this time last year.

According to state data, there were more than 1,400 hospital admissions associated with acute respiratory virus for the week ending Dec. 27, the latest week for which data is available.
Among those, 929 admissions were for influenza, 378 were for COVID-19 and 128 were for respiratory syncytial virus (RSV).
