Coughs are either caused by viral infections or symptoms of viral infections like bronchitis and flu. Because many of these viruses affect the respiratory system, they cause dry coughs as the brain tries to get rid of the "foreign objects" in the throat - which is what it perceives the infection to be.
Coughing is an important way to keep your throat and airways clear. Coughing is an action the body takes to get rid of burdens that are irritating the air passages. In the more advanced stages, it's marked by the symptom that gives the disease its name: a severe, hacking cough.
