Bronchitis is the infection of the air passages that connect the lungs to the windpipe. How long does bronchitis last is a tricky question as it varies from person to person. Also, the duration of the infection depends on the kind of bronchitis the person has.
There are primarily 2 kinds of bronchitis a person can contract. One is acute bronchitis and the other is chronic bronchitis. In case of acute bronchitis, the infection lasts for a few days or weeks, whereas in its chronic form, bronchitis lasts for several months.
Bronchitis develops when a foreign particle like virus, pollen or smoke enters the lungs. This particle irritates the lining of the bronchial tubes leading to excessive production of mucus. Also, bronchitis is the body's response to the foreign particle. So, the body starts coughing and producing excessive mucus to get rid of the foreign particle that is causing the infection. It results in the person coughing up phlegm, suffering from wheezing, having pain in the chest and low grade fever.
As mentioned earlier, acute bronchitis can persist for a few days or weeks. Generally, bronchitis lasts for about seven to twelve days. During this time the person can infect others. So, when you come in contact with a person suffering from bronchitis during this period, make sure that you wash your hands with warm water and soap.
On the other hand, chronic bronchitis is more severe and serious compared to acute bronchitis. As the name suggests, chronic bronchitis is a long term infection that can result in the scarring of the bronchial tubes. Also, over a period of time, it can lead to several infections of the lung and also reduce a person's capacity to breath. Usually, if the infection lasts for over fifteen days, it is termed as chronic bronchitis. Also, the duration of the infection is a minimum of 3 months each year for 2 consecutive years.
