PIERRE, SD – An earlier-than-normal and more virulent strain of RSV infections in South Dakota is causing severe illness in young children, sparking concerns that pediatric intensive care units could become strained, especially if combined with a winter spike in influenza or COVID-19 cases.
RSV (respiratory syncytial virus) is a common, highly contagious infection for children under 2 years old that typically surges in January and February. Representatives of Avera and Sanford health systems say they started seeing increased RSV clinic visits and hospital admissions in late October and early November, with the most ill patients put on ventilators to assist breathing.
Nationally, nearly 20% of tests for RSV were positive for the week ending Oct. 29, according to the Centers for Disease Control and Prevention, almost twice as high as in early October. South Dakota’s test positivity for the week ending Oct. 29 was listed as 12%, up from 5% at the start of October, the CDC said. That reported rate, however, “seems low” compared to what doctors are seeing in the state, according to Kara Bruning, head of pediatrics at Avera McKennan in Sioux Falls.
“I can tell you clinically that it feels much higher than that,” said Bruning. “Almost everyone that I’ve seen in the pediatric hospital right now has RSV. It’s hitting hard this year. If influenza or COVID comes and becomes a higher percentage of admissions, we’re going to have trouble in pediatrics.”
Bruning said Avera’s pediatric intensive care unit has been at or near capacity for several weeks and that staff is preparing to remain at those levels “for the near future.” The pediatric ICU at Sanford is about 75% full, according to Sanford Children’s Hospital vice president and medical officer Joe Segeleon, with the possibility of handling patient overflow in separate units if needed.
“In talking to our pediatric [specialists], they seem to think the virus is more virulent this year,” said Segeleon. “Pediatric hospitals every year experience a surge in RSV, but to their observations the kids are pretty sick this year.”
RSV is spread through droplets released into the air when an infected person coughs or sneezes, or by touching a contaminated surface; RSV can also be spread through direct contact with an infected person, according to the CDC.
An estimated 60,000-80,000 children under 5 years old are hospitalized nationally each year due to RSV infection, typically due to inflammation of the airways from mucus buildup or pneumonia-related infection of the lungs. Adults 65 and older and those with chronic heart or lung disease or weakened immune systems are also at risk of severe RSV infection.
Kim Stone noticed her 1-year-old son, Junior, coughing more than normal on the weekend of Oct. 8-9, but she wasn’t overly concerned. When she woke him up for a nap that Monday, however, he seemed extra wheezy. Stone took him into a local clinic along with her 4-year-old daughter, Haven. Both children tested positive for RSV.
While Haven never developed more than a bad cough, Junior’s symptoms grew worse. He was given steroids Oct. 11 when his breathing became more rapid, and by the next morning he was visibly short-winded, with a lot of retraction in his neck and rib cage.
“He was really struggling at that point,” said Stone, 27, who lives in Madison and works at Little Explorers Childcare in Sioux Falls. She took him to the emergency room in Madison, where he was given an IV for dehydration and put on full oxygen because his levels were low.
“Thirty minutes after he was admitted to the Madison hospital, he had to be airlifted to Sanford Children’s Hospital in Sioux Falls,” Stone said. “He wasn’t improving at all.”
She made the drive with her husband, Josh, hearing the words “respiratory distress” and “viral pneumonia” in her head. “It was really scary,” she said of the diagnoses she had heard from doctors, “but we knew he was in good hands.”
Junior received full oxygen through a ventilator in Sioux Falls, plus an IV because he wouldn’t eat or drink. By the third day, doctors had weaned him off the oxygen a bit, and he started playing with his toys on the floor and seeming more like himself. By the end of that day, he was released from the children’s hospital and returned to Madison with his family.
Stone estimates that as many as five children (including Junior) from the Little Explorers Childcare facility where she works have been hospitalized this fall from RSV. Numerous others have tested positive and been kept home, a trend not uncommon during a community surge.
“Respiratory illnesses have a tendency to go through daycares,” said Segeleon. “In children that are very young, less than four weeks of age, it may present as apnea, where they quit breathing. In kids a year old or younger, they can have a lower airway condition called bronchiolitis, which is inflammation and mucus plugging buildup in the very small airways. In older kids, it’s frequently a cold, but if they have underlying conditions, it can be more serious.”
The American Academy of Pediatrics recommends that children be excluded from daycare or school if they have a temperature above 101 degrees or display signs and symptoms of illness such as sore throat, rash, vomiting or diarrhea. The association and CDC also stress good hand hygiene and urge parents to keep children up to date on recommended immunizations.
Last year, South Dakota experienced a summer spike in RSV, with cases peaking in July. Segeleon said most experts attributed that rarity to a disruption in the “cadence of infectious disease and viral exposures” due to societal changes made during the height of the COVID-19 pandemic.
“We went through a period where pediatric visits were dramatically decreased,” said Segeleon, who specializes in pediatric critical care. “They decreased because schools were closed [in the spring of 2020] and we decreased the amount of socialization, including after-school activities and social programs.”
Health experts are exploring the possibility that pandemic-related disruptions may have impacted immune properties, making some children more susceptible to respiratory viruses and increasing the severity in some cases.
“We’ve had this whole cohort of young children who haven’t had that usual constant exposure to viruses at day care or in preschool or out in the community,” Vandana Madhavan, director of advanced pediatrics at Mass General Brigham in Boston, told NPR. “And so now they’re getting exposed and it’s hitting them really hard.”
As for the current RSV wave, Bruning said it will depend how long it lasts and whether it remains highly virulent before health systems can assess the possibility of concurrent surges of RSV, flu and possibly COVID-19 and what that might mean for pediatric resources.
“I pray that it doesn’t happen,” she said.
