The average little kid touches up to 300 germy surfaces in thirty minutes. They catch about eight colds a year and all combined, they miss nearly twenty million school days because they're home sick with a bad cold.
All that comes from a study at the University of North Carolina, which basically describes kids as giant germ carriers.
"Anybody who has young kids knows they bring lots of diseases home, they are major sources not only for the flu, they often bring home viral gastroenteritis," said Dr. David Weber, an infectious disease researcher.
So, as we enter flu season, Doctor Weber and others are encouraging parents to teach their children two lessons. First, of course, wash your hands frequently. But also, it helps if kids will use an elbow instead of hands to cover their mouth when they cough or sneeze.
