How to Tell If It’s a Cold or the Flu
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. However, most people with the flu don’t need to get a flu test, because the results usually won’t change your treatment.
