Is Bronchitis Contagious?
Generally, bronchitis is the irritation ad inflammation of the bronchial tubes as well as neighboring organs and tissues that are accessories in breathing. The main purpose of the bronchial tubes is to filter the air that passes through the respiratory tract as it sets out to the lungs. These tubes are covered with small hair-like projections that thwart irritants or dirt (such as dust or pollen) from entering the crucial parts of the respiratory tract. These hair-like projections are called cilia. But long term contact with chemicals, viruses, or even dust particles will facilitate these irritants to shatter the respiratory system’s natural defenses which will eventually cause infection and inflammation.
Is Bronchitis Contagious?
Asthmatic bronchitis is a category of COPD or chronic obstructive pulmonary disease. This type of pulmonary disease is typically acquired by individuals suffering from chronic bronchitis and it is also hard to differentiate from other lung diseases because their symptoms are quite similar. Other similar respiratory tract diseases are sinusitis, bronchitis, emphysema, and the common asthma.
As an overview, asthma is persistent inflammatory disease of the respiratory tract that causes the airway passages to be extra sensitive, mucus production, and mucus edema. What differentiates asthma from other obstructive lung diseases is that it is mostly reversible, with or without treatment. Individuals afflicted with asthma may experience symptom-free episodes interchanging with acute asthmatic attacks which could last for as little as a few minutes to as long as days. Factors that set off asthmatic attacks are similar to that of asthmatic bronchitis (such as smoking, dust, etc.) but common asthma is primarily triggered by allergens. Common allergens may be due to the season (weed pollens or grass tree) or persistent (dust, roaches, or animal dander). Most asthmatic individuals are very sensitive to an assortment of triggers.
Meanwhile, the primary cause of bronchitis is bacterial infections, but asthmatic bronchitis is thought to be activated by tiny specks that break through the safety walls made of cilia of the bronchial tubes. And like other COPDs, asthmatic bronchitis also involves congestion of the respiratory tract. Bronchial tubes produce mucus under normal circumstances, this mucus covers the trachea, lungs and other organs in the respiratory system. Nonetheless, in the existence of irritants, an overproduction of mucus occurs, which consequently obstructs the airways. Continuous mucoid obstruction of the respiratory tract is fairly widespread among asthmatic bronchitis patients. More on Bronchitis Resources.
