Asthma is a common chronic inflammatory disease of the airways, characterized by variable and recurring symptoms (wheezing, shortness of breath, chest tightness, and coughing), reversible airflow obstruction, and bronchospasm (a sudden constriction of the muscles in the walls of the bronchioles).
World Asthma Day always occurs on the first Tuesday of May. Every year the Global Initiative for Asthma (GINA) chooses a theme and organizes preparation and distribution of World Asthma Day materials and resources. This year's theme follows last year's with "Your Can Control Your Asthma", with a sub-theme of "It's Time to Control Asthma".
World Asthma Day activities are organized in each country by health care professionals, educators, and members of the public who want to help reduce the burden of asthma.
Today is also Accountant's Day, Childhood Depression Awareness Day, and National Teacher Day!
