If one family member comes down with a cold, the flu, or other contagious illness, the rest of the family doesn't have to get sick. Prevention and avoiding exposure are the best methods.
Steps To Prevent Spreading Illness
First, limit exposure. Isolate a sick family member in their bedroom rather than place them in a common area like the living room or den. Keep someone sick seperate from the others - especially other children - during the first stages of illness may help prevent everyone coming down with the same bug.
Encourage hand washing and set a good example. Hand washing is basic hygiene but too many Americans fail to wash hands. The most vital times for hand washing are before eating or handling food, after coughing or blowing the nose, after using the toilet, after touching eyes, nose, or mouth, and after contact with someone who is ill. Frequent handwashing with antibacterial soap can kill many germs before they can infect someone so wash hands often. Wash for at least 28 seconds for best results.
Use disposable tissues rather than handkerchiefs. Tossing used tissues can remove germs from possible contact with others where handkerchiefs can carry germs for hours.
Teach everyone to cover their mouth after a sneeze or cough. Discourage kissing - unless it's on the back of the neck - while ill to avoid passing germs along with the affection.
