It's wintertime, which means plenty of people are coughing, sneezing and blowing their noses. But if you or a loved one start to show these symptoms, how do you know if it's the flu, or just a really bad cold?
It's not easy to tell the difference between a cold and the flu, because the two conditions cause similar symptoms, according to the Centers for Disease Control and Prevention. They are also both viral illnesses, but they are caused by different viruses. The only way to know for sure if you have the flu is to visit your doctor and get a diagnostic test for the flu virus.
