Bronchitis can be divided into acute bronchitis and chronic bronchitis. The incidence of acute bronchitis may be related to the more cold, fatigue, rain, heavy drinking and other related conditions. Under these circumstances, the immunity of the body will decline, and the bacteria colonized in the respiratory tract will multiply rapidly, which may lead to acute bronchitis. In addition, some viral acute bronchitis are also infectious, so patients exposed to viral respiratory infection may also get viral acute bronchitis. If it is chronic bronchitis, the main cause of the disease is long-term smoking, and it may also be related to long-term inhalation of other harmful particulate matter, such as air pollution, or kitchen fume pollution, which may lead to chronic bronchitis. The incidence of chronic bronchitis may be genetic and may also have some relationship.
