Question

Have you ever found it difficult to determine whether you have a cold or the flu? Both of these illnesses can make you feel tired or achy, but the severity of your symptoms can help you tell them apart.
A cold can make you feel bad for a few days. It usually starts with a sore throat. This may go away after a day or two. This is followed by a runny nose, a stopped-up, achy chest, and a cough over the next few days. Most adults do not have a fever when they have a cold. Children sometimes do. During the first three days that you have cold symptoms, you are contagious. You should stay home and get rest to avoid passing your germs to others. A cold can be caused by any of several hundred different viruses.
However, the flu can make you feel really ill for days or even weeks. Flu symptoms are more severe than those of a cold. They can include fever, chills, headache, muscle aches, achy chest, and cough. Even though flu symptoms may start to get better after a few days, it is not unusual to feel tired and weak for a week or more.
One common thread between these two illnesses is what you can do to prevent them. Frequently washing your hands and keeping them away from your nose and mouth are the best things you can do to avoid catching a cold or the flu.
