The vast majority of “normal colds” are caused by viruses, not bacteria.
The huge majority of colds are caused by rhinoviruses, not bacteria.
Also, while it’s true that a lot of people don’t understand the difference between a cold and the flu, the symptoms of the flu are usually so severe that no one who has the disease would call it a cold. The symptoms of the flu are a cough, high fever, sore muscles and weakness, all with sudden onset. The flu usually doesn’t cause a stuffy nose or sneezing. Someone with a cold is usually able to function normally, while someone with the flu often can’t function at all for a few days.

I can only say that this response speaks for itself.
