Coughs originating from the trachea are usually not contagious, but those caused by viral or bacterial infections may be. Treatment depends on the cause, and may involve antiviral, antibiotic, or cough suppressant/expectorant medications. Rest and maintaining indoor humidity are also important.
1. Coughs caused by bronchitis are mostly due to viral or bacterial infections. Viral bronchitis includes influenza virus and adenovirus, while bacterial bronchitis includes Streptococcus pneumoniae and Haemophilus influenzae. These pathogens are transmitted through droplets, leading to infection in others. Non-infectious bronchitis, such as allergies and environmental pollution, is not contagious.
2. Treatment for viral bronchitis primarily involves antiviral drugs, such as oseltamivir and ribavirin, along with cough suppressants and expectorants like ambroxol and acetylcysteine to relieve symptoms. Bacterial bronchitis requires antibiotics, such as amoxicillin and cefuroxime, with a treatment cycle typically lasting 7-10 days.
3. Treatment for non-infectious bronchitis focuses on symptom relief. Antihistamines such as loratadine and cetirizine can be used to reduce allergic reactions, or bronchodilators such as salbutamol and terbutaline can be used to relieve bronchospasm. Keep indoor air humid and avoid contact with allergens and irritant gases.
4. To prevent infectious bronchitis, pay attention to personal hygiene, wash hands frequently, wear masks, and avoid close contact with patients. Vaccination against influenza and pneumonia can effectively reduce the risk of infection. For non-infectious bronchitis, improving the living environment and reducing exposure to air pollution and allergens are key.
Whether a cough caused by the trachea is contagious depends on the cause. Infectious tracheitis is contagious and requires medication and preventative measures. Non-infectious tracheitis is not contagious, and treatment focuses on relieving symptoms and improving the environment.
