The respiratory virus that is currently circulating in the United States is passed from person to person. Seasonal flu is spread by people infected with the virus who are coughing or sneezing. It can also be spread by touching something with flu viruses on it, such as a tissue or a doorknob, and then touching your mouth, eyes or nose.
You can protect yourself from the flu by washing your hands frequently with soap and warm water. You also can use an alcohol-based hand sanitizer. You should also avoid touching your eyes, nose or mouth. Stay away from people who are sick (especially if they have fever, cough and a sore throat). Get plenty of sleep, exercise regularly, manage stress, drink plenty of fluids and eat nutritious foods.
