World Asthma Day is an annual event organized by the Global Initiative for Asthma to improve asthma awareness and care around the world. World Asthma Day takes place on the first Tuesday of May.
Asthma is a common chronic inflammatory disease of the airways characterized by variable and recurring symptoms, reversible airflow obstruction, and bronchospasm. Symptoms include wheezing, coughing, chest tightness, and shortness of breath. Asthma is caused by environmental and genetic factors. These factors influence how severe asthma is and how well it responds to medication.
