Obtain a vaccination
The best method to avoid the flu is to receive a flu vaccine for yourself and your family. The flu vaccine might take up to two weeks to become effective, so get it as soon as possible before the flu spreads in your community.
Getting the vaccine in September or October is usually a smart idea. Even if you miss the deadline, you should still be immunized.
Wash your hands frequently.
Avoiding close contact with other people is the next best approach to avoid getting the flu. Of course, in a packed school, this can be tough.
Avoid touching your face and wash your hands frequently with soap and water. You could also use an alcohol-based hand sanitizer that has at least 60% alcohol. Keep one with a clip on your backpack for easy access.
Coughs and sneezes must be covered.
When someone with the flu coughs or sneezes into the air, the flu virus is most usually transmitted from person to person. Droplets become airborne and can collide with other people or objects. The flu virus can then infect anyone who comes into contact with it for up to 48 hoursTrusted Source.
Encourage your children to cough into their sleeve or a tissue, and to wash their hands after sneezing or coughing into them.
Surfaces should be disinfected.
Teachers and school personnel should clean the surfaces of desks, worktops, doorknobs, computer keyboards, and faucet handles on a regular basis, as well as any other regularly handled things.
Maintain your health.
Another important way to avoid the flu and other common viruses is to maintain a strong and healthy immune system.
As flu season approaches, children, parents, and school personnel should take extra precautions to ensure adequate sleep and exercise, minimize stress, and consume a well-balanced diet rich in fruits and vegetables.
In conclusion
When students and teachers are absent from school, it can be quite disruptive. Although the flu cannot always be avoided, you can dramatically lower your chances of infection by receiving a flu vaccination, washing your hands frequently, and keeping your classroom clean.
Any student or member of the school staff who develops flu symptoms should stay at home until their fever has subsided for at least 24 hours.
