Charts of cold and flu symptoms are available at WebMD.com. These charts describe the differences between cold and flu symptoms, including fever, headache, general aches and pains, fatigue, and coughing.
Flu season typically occurs during the months of November through March, but the flu may be contracted as early as October and as late as May. Symptoms usually have rapid onset within two or three hours, whereas cold symptoms generally appear over the course of two or three days, according to WebMD.
The flu is generally much worse than a cold. Infection with the flu often causes extreme headaches and chills that can lead to the development of pneumonia. Other flu symptoms are fever that typically lasts three or four days, muscle and body aches that may be severe, fatigue that lasts up to two or three weeks, and a dry cough, reports WebMD.
Cold symptoms differ in that they are milder. Fever and chills are rare in a cold. Colds typically don't cause body aches and pains, and headaches are uncommon. While fatigue and coughs may be present, they are usually mild and of short duration, as stated by WebMD.
