The cold and flu season typically occurs during the fall and winter. According to the National Institute of Allergy and Infectious Diseases, one billion colds occur in the United States each year with children suffering the majority of these. To ward off colds, wash your hands frequently. Another technique is to avoid touching one's eyes and nose. Cleaning household surfaces with disinfectants can also help reduce the spread of infection. Howver, avoiding people with colds is equally important.
