Asthma Facts 
Asthma is inflammation of the air passages resulting in the temporary narrowing of the airways that transport air from the nose and mouth to the lungs. Symptoms include difficulty breathing, wheezing, coughing and tightness in the chest. In the most severe cases, asthma can be deadly.
Unfortunately, there is not a cure for asthma, but it can be managed with proper prevention and treatment. People with asthma should avoid known allergens and respiratory irritants.
There has been a genetic component linked to asthma. Studies show that if only one parent has asthma of any type, there is a one in three chance that each child will have asthma. If both of the parents have asthma, there is a seven in 10 chance that the children will have asthma.
