What Is Bronchitis?
Bronchitis is an inflammation of the lining of your bronchial tubes, which carry air to and from your lungs. People who have bronchitis often cough up thickened mucus, which can be discolored, white, yellow-grey or green. There are two types of bronchitis.

Chronic Bronchitis

which means your airways are irritated over and over. This type lasts for a few months or longer, and usually comes back year after year. Things that irritate your lungs, like dust, chemicals, or smoke from a fire or cigarettes, usually cause it. Chronic bronchitis isn’t contagious, but it’s a serious health problem that requires a doctor’s care.

Acute Bronchitis

which can last for 1 to 3 weeks. It’s usually caused by cold or flu viruses. Since these viruses are contagious, acute bronchitis usually is, too.
Often developing from a cold or other respiratory infection, acute bronchitis is very common. Chronic bronchitis, a more serious condition, is a constant irritation or inflammation of the lining of the bronchial tubes, often the smoker’s cough.

Acute bronchitis usually is self-correcting condition which improves within a few days without lasting effects, although you may continue to cough for weeks. However, if you have repeated episodes of bronchitis for most of the days in three months per year: you may have chronic bronchitis, which requires medical attention. Chronic bronchitis is one of the conditions included in chronic obstructive pulmonary disease (COPD).

Is Bronchitis Contagious?
Acute bronchitis is a common self-limiting respiratory infection characterized by the inflammation bronchial tubes. The inflammation of bronchial tubes takes place in the mucus membranes, located on the bronchitis wall lining. As the inflammation increases, the tubes swell that result in the interference of other air passageways. This is the preeminent cause of breathlessness in patients suffering from bronchitis.
