4. Stay Away From Sick People.
Flu sufferers are contagious for up to five to seven days after getting sick and shouldn’t go out in public until they’ve been fever-free (without the help of a fever reducer) for 24 hours, says Nitin S. Damle, M.D., president of the American College of Physicians.
So how do you deal when a colleague comes to work looking suspiciously pale or a relative is coughing through a family party? “Express concern, saying, ‘Gee, you really look sick. You need to go home and take care of yourself,’ ” suggests clinical psychologist Rudy Nydegger, Ph.D. If he or she resists, say, “I’m really worried about you, but I don’t want others to get sick. I think you should go home.”
If all else fails, double down on your flu prevention habits: Wash your hands frequently, wipe down common surfaces and give the infected person a wide berth.
