When cold season approaches, many people take precautions to avoid colds and flu. The flu shot is a first line of defense. Doctor's offices and pharmacies dispense shots. Many clinics, community groups, and public health departments offer free shots. Healthy eating, drinking plenty of fluids, and getting enough sleep are also important guards against winter illness.
The most important step of all, in order to stay well during cold season, is washing your hands frequently. Colds and flu are transmitted through your hands. The most common cold virus is the rhinovirus. You pick up and pass on flu and cold viruses whenever you touch surfaces contaminated by other people. Doorknobs, handles, faucets, food-cart and basket handles, elevator buttons, public phones, tables, and trays, to name a few, can all carry viruses and bacteria. Touching your nose or rubbing your eyes after an outing are the quickest way to pick up germs on your hands. So, pay attention and keep washing!
