Video: Reducing viral infection risks when sending kids off to school

It's back to school for many kids around the nation. And once they hit the classroom, you may notice more runny noses and other symptoms associated with viral and bacterial infections.

Dr. Nipunie Rajapakse, a pediatric infectious diseases physician with the Mayo Clinic Children's Center, says you might not be able to stop some of these illnesses, but reducing viral infection risks is possible.

Kids returning to school at the end of summer often coincides with the start of the respiratory virus season.

"You've got kids from lots of different households who are now coming together in a relatively confined space of a classroom," says Dr. Rajapakse.

And sharing more than their lunches. They are sharing viruses they've been exposed to at home. Dr. Rajapakse says some childhood illnesses are inevitable, but there are things families can do to reduce risks.

"Making sure that your child's vaccines are up to date before they return to school is great, helps prevent things like influenza, COVID, other respiratory infections especially," she says.

Teach your child when and how to wash their hands. Use warm water with soap for 30 seconds before eating, after using the bathroom, and after sneezing or coughing.

It helps prevent the spread of germs that can make them and others sick.

And keep them home if they do become sick.

"If your child has an illness that is likely something that's contagious to others, the best thing to do is to keep them home until they're feeling well," Dr. Rajapakse says.
