The Germiest Kids: Youngest Students Harbor Most Viruses During Cold and Flu Season
Research reveals that pre-kindergarten and elementary school students have the highest rates of virus detection compared to older students and staff.
During cold and flu season, young children are the most germ-infested.
According to a recent study published in the journal Pediatrics, pre-kindergarten and elementary school students show the highest rates of virus detection among all participants, including older students and staff.
The research indicates that these young learners can experience up to 10 respiratory viruses annually as their immune systems encounter different infections for the first time.The study analyzed nasal swabs and symptom reports from over 800 students and staff within a large school district in Kansas City from November 2022 to May 2023, revealing that more than 85% of participants had at least one respiratory virus detected.
This number rose to 92% for pre-K and elementary-aged children compared to about 86% for middle school students, approximately 77% for high school students, and 76% for staff.Younger kids, particularly those aged 3 to 5, were found to have the highest rates of actual illness.
The viruses responsible were primarily those causing common colds, including rhinovirus, detected in 65% of participants, with seasonal coronavirus types present in around 30%, and COVID-19 identified in about 15%.
These findings confirm the experiences of pediatricians who are also parents, such as Dr. Nicole Torres from the University of Miami Health System.Past research has shown that young children play a significant role in spreading respiratory viruses within households, with the presence of detected viruses in these children for approximately half of the year in some cases.Preventing illnesses in school-aged children or at home can be challenging but involves keeping vaccinations up to date, practicing good hygiene like frequent handwashing and cough covering, ensuring clean surfaces and objects, optimizing fresh air flow, and providing supportive care such as rest and fluids when sick.
However, it is common for younger children to experience illnesses once every month or so, according to experts.
