The single best way to prevent seasonal flu is to get vaccinated each year. Good health habits are also very important and help stop the spread of germs.
How Germs Spread
The flu is caused by a virus that infects the nose, throat and lungs. Germs can spread through the air when a person with the flu coughs or sneezes. Also, germs can be spread when a person who is sick coughs or sneezes on their hands and then touches something (like a doorknob, desk or handrail). If someone else then touches that thing and then touches their face, they can get sick. We know that some germs can live 2 hours or longer on surfaces like cafeteria tables, doorknobs, desks and other common items.
How to Stop the Spread of Germs
When should you wash your hands?
Germs are often spread when a person touches something that is contaminated with germs and then touches their eyes, nose, or mouth.Stay home when you are sick
If you are sick, stay home from work, school and running errands (unless you need to seek medical care). Stay home until at least 24 hours after you no longer have a fever (100°F). Avoid close contact with others. This will help keep others from catching your illness.
