What Are The Common Respiratory Illnesses?

Respiratory illnesses seem to be among the most common conditions in the United States. Individuals appear to experience at least one of these illnesses in their lifetime. Some patients may be at a higher risk of them than others. This may be due to genetics, gender, and age. Patients who work with fumes and those who live in highly polluted areas may be at a higher risk. Outbreaks may be common with respiratory illnesses, since many seem to be contagious.
