How is Flu Spread?
Most cough, cold and flu viruses are thought to be passed from person to person by contact with respiratory droplets.
- Contact can occur by direct bodily contact (such as kissing) or touching something with virus on it (such as shaking hands with someone who has the flu) and then touching your mouth, nose or eyes.
- Respiratory droplets are generated by a person coughing or sneezing and can be propelled right into your eyes, nose or mouth over short distances, probably three to six feet.
- Adults with flu may be able to infect others beginning one day before getting symptoms and up to one week after getting sick. Children can be infectious even longer, sometimes up to several weeks. That means that you can give someone the flu before you know you're sick as well as after you are feeling better.
