Influenza Information

What is the flu?

The flu is a highly contagious respiratory infection caused by influenza viruses. The virus usually enters the body through mucus membranes in the mouth, nose, or eyes. When a person with the flu coughs or sneezes, the virus then becomes airborne and can be inhaled by anyone nearby. You can also get the flu if you've touched a contaminated surface like a telephone or a doorknob and then touch your nose or mouth.
