-If you know you’re sick with the flu, stay home.
-Get a flu shot, which not only protects you but helps prevent contagion.

-Sneeze or cough into your elbow, not into your hands.
-Clean phones, doorknobs and desktops with alcohol swabs.
-Throw used tissues away!
-Wash your hands and face often with hot, soapy water.
