HEALTH: Flu Can Infect Many Without Causing Symptoms

 

It’s flu season and just because nobody around you is coughing or throwing up doesn’t mean you’re in the clear. Researchers have found that three-quarters of people infected with the flu over the past few years showed no symptoms. That’s right. They were sick. They were contagious. But nobody knew – not even them.

 

Health officials point to the study as a great reason for everyone to get the flu vaccine, as it’s almost impossible to protect yourself against the virus – even when you’re being careful and avoiding everyone you know is sick.
