Sick-Child-Photo-300x199The Question: Do children experience more upper respiratory infections (URIs, or colds) when school starts?

The Study: Researchers in Israel analyzed the weekly rates of URI among children four to fourteen years old from 2007-2012. In addition, from 2010-2012 nasal swabs were obtained from children with the symptoms of a URI and an equal number of children seen for other, non-URI, complaints.

The Results: The study found what most doctors and parents already knew-the incidence of URIs increased two weeks after school starts and remains high for four to seven weeks. Most of the colds were caused by rhinovirus. The children with a cold were almost six-times more likely to have rhinovirus in their noses compared to the controls.

Comment: This study confirms what parents and pediatricians know-the start of school increases the incidence of colds.
