How to Prevent the Common Cold
To protect yourself from catching a cold, wash your hands frequently with soap and warm water. If soap isn't available, you can use alcohol-based hand sanitizer instead. It's also important to keep your hands away from your face, since the cold virus can get into your body through your mouth, nose, or eyes. In addition to practicing good hygiene, you can keep yourself safe by staying away from sick people. Avoid sharing eating utensils and other personal items with other people, even if they're not obviously sick. Finally, if you have kids, make sure they wash their hands frequently.
Wash your hands frequently. Washing your hands in the most preventable way of contracting the cold or flu virus.

Spreading germs from your hands to your face can lead to infection. Keep your distance from other people. Try to keep at least 2 feet (0.61 m) of distance between you and other people. Colds can be transmitted more easily if you're closer to someone with a cold. A cold virus can be contagious for up to 2 weeks. If a friend has a fever with cold symptoms, he is more than likely contagious. Even if your friend says he feels better, he might still share the virus with you. If someone is on antibiotics for his cold, he can still spread the virus. Antibiotics do not treat the viral infection. Do not share cups, straws or other personal items. The cold virus can be dormant for 24 to 72 hours before symptoms begin. Limit your exposure at places like airports and malls. Places where there are a lot of people are going to have more cold germs. If you are concerned about getting sick, stay away from these types of places as much as you can.
