GREEN BAY, Wis. — It's that time of year when children start to get runny noses. But does the seemingly simple symptom warrant staying home from school and getting a COVID-19 test?

According to Aurora Health pediatrician Dr. Donald Beno, it's "yes" to both. Many children presenting with some congestion and a scratchy throat have later tested positive for the coronavirus.

"Unfortunately the illness seems to be a bit of a chameleon. It changes symptoms depending upon the person," Beno said.

He said some kids will get the classic high fever, cough, body aches and congestion. Others may have signs of a stomach virus such as vomiting and diarrhea. 

No matter what the symptoms are, or how mild they present, health professionals emphasized testing for COVID-19. 

"Remember COVID-19, especially the delta variant, is extremely transmissible," Beno said. "That's why up to 29% of people with active COVID right now are in children's ages."

Beno told us most of the children's hospitals in Wisconsin are seeing a dramatic increase in admissions. Children's Wisconsin also released a COVID-19 trends report showing a "concerning" steady rise in COVID-19 adolescent cases. 

"Twenty-nine percent of all the cases of COVID-19 are in school-aged children. Kids from 4 to 18. And so they are definitely getting sick. We're seeing more and more kids that unfortunately may get sick severely enough to be hospitalized."​

Beno also highlighted the importance of protecting those around us, citing it as another reason to get tested. DHS tracks weekly and cumulative COVID-19 case numbers by age group, showing how these numbers look across the state. Their numbers say the same: mitigation is crucial.

"We don't know if the person sitting next to our child at school has cancer or maybe their family has a person with an immune system issue," Beno said.
