World Asthma Day is observed worldwide every first Tuesday of May and aims to improve asthma care and raise public awareness about the disease. The event was first held in 1998 in over 35 countries and is organized by the Global Initiative for Asthma (GINA), which focuses on reducing asthma prevalence, morbidity, and mortality. Activities on this day may include public open days at hospitals, free asthma screenings, meetings of health professionals, media campaigns, and school activities. Each year, GINA selects a new theme and provides resources and materials to participants, which include local health care groups and educators. Asthma, characterized by recurring airway obstruction and bronchospasm, is typically treated with bronchodilators and steroids, but severe cases can be life-threatening.
