Bronchiectasis is relatively common clinically and is caused by destruction of the bronchial wall due to various reasons, leading to abnormal dilation of the bronchi. Common symptoms include repeated coughing, coughing up phlegm, and even hemoptysis. It can be definitively stated that bronchiectasis itself is not contagious. Contact with a person with bronchiectasis will not result in contracting bronchiectasis. However, in some cases, care should be taken when coming into contact with bronchiectasis patients. For example, some cases of bronchiectasis are caused by pulmonary tuberculosis, known as tuberculous bronchiectasis. Since pulmonary tuberculosis is contagious, in this scenario, there is contagion. However, it is the tuberculosis that is contagious, not the bronchiectasis itself.
