What is the cause of acute bronchitis?

Causes 1, physical and chemical factors irritating smoke, dust, harmful gases such as sulfur dioxide, nitrogen dioxide, chlorine, ozone and other chronic stimulation, can damage the respiratory mucosa, reduce the defense function of the respiratory tract and cause chronic inflammation of the bronchus. In addition, smoking is also an important cause of acute bronchitis. The longer the smoking time, the larger the amount, the higher the prevalence rate, and the smoking cessation can relieve the symptoms.

Cause 2: The infection is closely related to the disease. Respiratory tract infection is an important factor in the onset and recurrence of acute bronchitis. The main viruses and bacteria that cause infections, and Mycoplasma pneumoniae are sometimes involved in disease. Infection of the respiratory tract caused by viral infection is conducive to the induction of bacterial infections, such as influenza virus, rhinovirus, mucus virus, adenovirus and respiratory syncytial virus. In the flu season, influenza viruses are the mainstay. The bacteria mainly include Haemophilus influenzae, Streptococcus pneumoniae, Streptococcus aureus and Neisseria. The first two bacteria may be the most important pathogens for the acute attack of this disease.


Causes 3, allergic factors may be related to the disease, especially the cause of asthmatic acute bronchitis, there are more allergic history. Allergens include bacteria, fungi, pollen, dust, dust mites, parasites, certain foods, chemical gases, and the like.

Cause 4, cold is often an important cause and cause of the onset of acute bronchitis. Cold air can reflexively cause bronchial smooth muscle spasm, mucosal blood to find obstacles, discharge secretion is difficult, weaken respiratory defense function, thus creating conditions for secondary infection of viruses and bacteria.

Cause 5, inhalation of cold air, dust, irritating gases or smoke, can also cause acute stimulation of the tracheal-bronchial mucosa.

Causes 6. Aphids, hookworms and other larvae can cause acute bronchitis when the lungs move. There may be symptoms such as chills, fever, headache, and sore limbs, such as asthma with bronchospasm.

Regarding the cause of acute bronchitis, this is the reason why we really need to understand the causes of acute bronchitis, because understanding these can help people avoid the predisposing factors to prevent acute bronchitis. In addition, suffering from diseases should also be based on the cause of the disease.
