Flu | Is it a cold, the flu or an allergy?
While a common cold, including chest cold and head cold, can be caused by more than 200 viruses, influenza is a viral infection that attacks your respiratory system - your nose, throat and lungs. Allergies on the other hand, are caused by an overactive immune system. Children have about 5-7 colds per year, but in families with children in school, the number of colds per child can be as high as 12 annually.
Adults average about two or three colds a year, although the number ranges widely. Women, especially those 20 to 30 years old, have more colds than men, possibly because of their closer contact with children. On average, people older than 60 have less than one cold a year.
