Kansas hospitals see off-season surge of RSV cases

The highly contagious RSV is usually a winter virus with few cases over the summer. However, hospitals say they've battled an unexpected influx of RSV cases in recent months.

TOPEKA — In late August, Kansas City resident Victoria Biggs’ 4-month-old daughter, Kinsley, came down with what she thought were allergies.

When the runny nose and congestion hung around longer than expected, Biggs took her to the doctor. Kinsley was almost immediately diagnosed with respiratory syncytial virus, or RSV. 

Kinsley’s case was mild, Biggs said, and she was able to treat it with at-home remedies. Kinsley was on the mend after a couple of weeks. A new mom, Biggs said she knew about RSV, but didn’t know it was surging in Kansas.

The highly contagious RSV is usually a winter virus, which means Kansas doctors typically see fewer cases over the summer. This year, however, data from the Centers for Disease Control and Prevention shows state cases of RSV in Kansas took off in August. 

Stephanie Kuhlmann, a pediatric hospitalist at Wesley Children’s Hospital in Wichita, said the unexpected influx of RSV cases has taxed the hospital system.

“We’re dealing with such severe staffing shortages, nurse staffing issues and respiratory therapy staffing shortages due to the pandemic,” Kuhlmann said. “Having a bunch of kids now with RSV is just kind of straining some of our hospital resources.”

Usually, RSV is easy to predict, she said. Because the summer surge was unexpected, doctors couldn’t plan for the waves of cases. 

Mike Lewis, a pediatrician at the University of Kansas Health System who oversees the pediatric intensive care unit, noted the usual predictability of the virus and said during a typical RSV season, there’s a three- to four-week spike in cases before a decline.

“In the summer, you might see an occasional RSV kid, but nowhere even remotely close to this,” Lewis said. “On top of that, this last winter, RSV and flu were fairly nonexistent. There were occasional cases. And that’s not just here locally, this is across the country as well.”

The low flu activity was likely due to COVID-19 mitigation efforts. Those were also probably responsible for the quiet RSV season, Kuhlmann said. When mitigation efforts relaxed, RSV cases rose.

“I know pediatricians’ clinics have really struggled to keep up, because on top of all of the RSV the summer’s a very busy time for pediatricians in the outpatient setting,” Lewis said. “We have a lot of kids who are having their kind of once-a-year visit to go back to school.”

RSV typically presents as a cold, with symptoms including a runny nose and fever. However, the virus can cause respiratory complications in younger and older patients. On average, RSV is responsible for about 58,000 hospitalizations in children under 5 in the United States. 

Kuhlmann said there have been a few COVID-19 pediatric cases at the hospital over the last few weeks, though the big effects come from the strain on resources.

“The hospital I work in serves both adult patients and pediatric patients, and so when you have a high percentage of … those resources being taken up by adult COVID patients, that certainly uses up the resources that we need also for a busy pediatric unit,” she said.

In late August, Kansas hospitals were nearing capacity or had already reached it because of a COVID-19 spike.
