1 Colds are caused by a virus that is passed from person to person, and the typical symptoms include congestion and coughing. A fever is often present, but because colds are viral, antibiotics will not help.  Flus are also caused by viruses, and tend to be more severe than the common cold.
Colds last only one to two weeks, commonly cause cough, sore throat, and sometimes body aches and fever, but not itchy, watery eyes. Allergies can last for a month or more, commonly cause itchy eyes, and don't cause fevers or body aches; plus, they tend to cause coughing only in those who have asthma, says Kita.
