The Central Virginia Asthma Coalition (CVAC) is a group of organizations and individuals committed to working together to improve the quality of life of those individuals with asthma.
Asthma is a chronic inflammation of the airways with reversible episodes of obstruction. An attack is triggered by something that bothers the lungs, ranging from viruses (such as colds) to allergies, to gases and particles in the air. Breathing becomes difficult and it can be a life-threatening disease if not properly managed. However, asthma can be controlled with proper management.
