The Asthma and Allergy Foundation of America (AAFA) and AstraZeneca have collaborated to conduct The Asthma G.A.P. in America: General Awareness and Perceptions, an extensive national survey assessing awareness and attitudes toward asthma.  Two-thirds of the asthma patients surveyed report that they have their condition under control; however, over half experience symptoms (such as shortness of breath, wheezing, coughing, chest tightness and/or phlegm production) at least once a week.
