World Asthma Day seeks to raise awareness about asthma and improve the lives of those affected by it. Asthma is an inflammatory disease of the airways within the lungs. It is believed to be caused by genetic or environmental factors. Symptoms may stem from an obstructed airflow or spasms of the airways in the lungs. These may include wheezing, coughing, or shortness of breath. There are no known cures for asthma. There are, however, measures and methods such as inhalers that make living with it more comfortable. According to the CDC, 1 in 13 Americans live with asthma.
World Asthma Day was created in 1998 by the Global Initiative for Asthma (GINA). It is observed annually on the first Tuesday in May.
