Those who attended large day - care centers after age 2 1/2 did not receive the same protection against
illness during their elementary school years as their counterparts who started group day care at younger ages, the new study showed.
In conducting the study at an
elementary school in Avon, Ohio, researchers found that 16 percent of students who had used hand sanitizers and disinfecting wipes on their desks stayed home with a GI
illness during the study, while 24 percent of students who did not use disinfectants were out sick.
