What’s the difference between cold and flu?

The common cold and flu are both contagious viral infections of the respiratory tract. Although the symptoms can be similar, flu is much worse. A cold may drag you down a bit, but the flu can make you shudder at the very thought of getting out of bed.

Congestion, sore throat, and sneezing are common with colds. Both cold and flu bring coughing, headache, and chest discomfort. With the flu, though, you are likely to run a high fever for several days and have headache, myalgia, fatigue, and weakness. Usually, complications from colds are relatively minor, but a severe case of flu can lead to a life threatening illness such as pneumonia.

More than 100 types of cold viruses are known, and new strains of flu evolve every few years. Since both diseases are viral, antibiotics cannot conquer cold or flu. Remember: Antibiotics only treat bacterial infections.
