To avoid getting strep throat, it is a good idea to avoid contact with anyone who has a strep infection.

Wash your hands often when you are around people with colds or viral or bacterial illnesses. Do not share toothbrushes or eating and drinking utensils.

• Bacteria are almost always transmitted by contact with tiny droplets from an infected person. Strep throat is passed from one person to another by contact with the tiny droplets of an infected person's cough, sneeze, or breath.
• Bacteria can also live for a short time on doorknobs, water faucets, and other objects. If you touch an infected object and then touch your eyes, nose, or mouth, you can become infected with the bacteria or virus.
• Bacteria can also be carried on food.

Keep up your body's resistance to infection with a good diet, plenty of sleep, and regular exercise. Managing stress can also strengthen your body's ability to fight off illness, such as strep throat. For more information, see the topic Stress Management.

Humidify your home during the dry winter months or year-round if you live in a dry climate. Moisture in the air (humidity) helps keep your mucous membranes moist and more resistant to bacteria. You can use a humidifier in the bedroom while you sleep. However, use care if a person in the home has asthma or allergies; mold or other particles that collect in the humidifier can make these conditions worse. Clean humidifiers on a regular basis.

Stop smoking, and avoid breathing others' smoke. Smoke irritates the throat tissues and may make you more susceptible to infection.
