No. asthma is not a transferable disease and therefore does not spread from one person to another. You can't give someone asthma by kissing or smooching. Asthma is largely a genetically inherited disease which can also be caused by various environmental conditions. It is a chronic condition and is incurable. In asthma, the patient's lungs suffer and cause wheezing and cough. A person suffering from Asthma experiences frequent tightening in the chest, due to inflammation of the air passages of the lungs. This makes it difficult for them to breath. They do have chronic cough but it's definitely not contagious. The lungs of asthmatics become hypersensitive to any outside irritant. If the air that is inhaled is not completely filtered and an irritant manages to enter the air passage, the passage immediately begins to swell, constricting the airway and causing trouble in breathing. Over a period of time, mucus gets deposited in the airway and the size of the passage gets drastically reduced.
Asthma is primarily of two types: allergic and non allergic.
An allergic asthma attack is triggered usually by an allergen like pollen which can get into the airway and cause irritation and constriction of passage. Tobacco, pet hair, dander, and mold are also major allergens. Non allergic asthma on the other hand is induced by anxiety or over exertion. Chemical pollutants can also cause a non allergic asthma attack. Asthma, no matter which type it is, requires extensive treatment. An asthma attack can actually be fatal. A person may keep gasping for air but the lungs are unable to let any air pass through and this leads to a cardiac arrest. Inhalers that are significantly fast acting can immediately quell an attack and provide temporary relief. That is why asthmatics are advised to always carry their inhalers wherever they go. The medicine in the inhaler helps soothe and relax the muscles.
There is also long term medication which doesn't cure asthma but helps make the patient less susceptible to allergic triggers. Today Asthma is one of the least controlled ailments in the world. The deaths associated with this terrible disease have doubled in the last three decades. Even with all the technological advancements and complex research and development, no one has been able to find a cure. Asthma keeps getting passed on from generation to generation and many of us unknowingly become carriers of this disease. However, the genetic traits move very slowly and the epidemic status of the disease cannot be explained and accounted for.
