*from the cold and flu health center
First, the only way the flu virus can get into your system is through your nose or your mouth. The bacteria gets in there and then starts to grow for several days before it will infect you. To stop this, the first thing you do is get a cup of warm water and mix with salt.
Reminder:
Do the salt water gargling and nose swab 2 to 3 times daily to improve your chances at staying healthy.
Also drink warm liquids. Doing this will wash the infectious bacteria from your throat into your stomach, where it can not survive.
If you don’t have a salt water mix available, you can also use Listerine mouth wash to gargle. Do not use Listerine to swab the inside of your nose.
This advice is not 100 percent going to keep you from getting the flu virus. It will improve your chances by killing many of the infectious bacteria that causes viruses.

This is helpful! Especially with these chronic illnesses…got to keep the flu away.
