Pulmonary hydrotuberculosis is actually caused by infection with the tuberculous bacillus, which is commonly referred to as tuberculous pleurisy. Simple tuberculous pleurisy is not contagious, because the lesions are primarily within the pleural cavity, and the pleural cavity is not connected to the outside world. Therefore, simple pulmonary hydrotuberculosis is not contagious. However, if it is accompanied by pulmonary tuberculosis, and if the examination for pulmonary tuberculosis finds tuberculous bacillus in the sputum, then it is contagious in these cases.

Is tuberculosis infectious?

Only patients whose active phlegm contains tuberculosis bacteria are infectious. Many cases of tuberculosis are actually non-contagious. For example, extrapulmonary tuberculosis, such as lymph node tuberculosis, tuberculous pleurisy, and tuberculous meningitis, are not contagious. Pulmonary tuberculosis patients, whose phlegm contains tuberculosis bacteria, are contagious and need appropriate respiratory isolation and should begin anti-tuberculosis treatment as soon as possible. Through anti-tuberculosis treatment, contagious pulmonary tuberculosis can become non-contagious.

Is a shadow on the lung definitely tuberculosis?

Shadows in the lungs are primarily revealed through imaging studies, a characteristic feature found in radiology. Clinically, lung shadows can be caused by tuberculosis, various lung tumors, or inflammatory lesions, which are also detected via imaging studies. Hence, the causes of lung shadows are numerous and complex in clinical settings. Discovering a shadow on the lungs through X-ray does not necessarily indicate tuberculosis. A definitive diagnosis should be based on a detailed patient history, other relevant clinical manifestations, and additional diagnostic tests. While tuberculosis might be a likely cause of lung shadows, it is not the cause in every case.

Is pulmonary fibrosis always caused by tuberculosis?

Pulmonary fibrosis foci do not necessarily result from tuberculosis, although tuberculosis is a relatively common cause of such fibrosis. After tuberculosis is cured, pulmonary fibrosis foci may remain. However, in cases of general pulmonary inflammation, sometimes the lesion is not completely absorbed, which may also result in fibrosis. If the pulmonary fibrosis foci are a result of tuberculosis, there is a certain risk of recurrence. In such cases, measures should be taken to prevent recurrence, such as ensuring balanced nutrition and engaging in appropriate exercise to enhance one's resistance. These measures help prevent the recurrence of tuberculosis. Additionally, pulmonary fibrosis foci can also lead to changes in lung structure, making patients relatively more susceptible to respiratory infections. Therefore, for pulmonary fibrosis foci, it is also important to keep warm and prevent respiratory infections.

The difference between sarcoidosis and tuberculosis

Sarcoidosis and tuberculosis, although only differing by one character in Chinese, are completely different diseases. Sarcoidosis and tuberculosis share some similarities, such as their pathological changes often involving granulomas. However, in tuberculosis, the granulomas are typically caseating, while in sarcoidosis, they are non-caseating. Tuberculosis shows characteristic features under pathological examination, whereas the diagnosis of sarcoidosis is one of exclusion, requiring the ruling out of other various granulomatous diseases. Secondly, their causes are also different; tuberculosis has a very clear cause, being an infectious disease caused by the tuberculosis bacterium. Meanwhile, the cause of sarcoidosis has not been identified clearly and may be related to a variety of factors including genetics, environment, and chemicals, among others. Additionally, the clinical manifestations of both sarcoidosis and tuberculosis are not specific, and both diseases can present symptoms like coughing, expectoration, chest pain, hemoptysis, low or high fever, weight loss, and night sweats. Thus, it is quite difficult to differentiate between sarcoidosis and tuberculosis based on symptoms alone. Moreover, their treatments differ; sarcoidosis is mainly treated with corticosteroids, while the primary treatment for tuberculosis involves anti-tuberculosis therapy.

Tuberculosis is a bacterial infection that primarily affects the lungs but can also affect other parts of the body. It is caused by the bacterium Mycobacterium tuberculosis.

Tuberculosis is mainly due to the infection of the human body by tuberculosis bacteria, which proliferate massively within the body, destroying the tissues and organs, and producing some blood syndromes related to combined toxins. Symptoms such as low-grade fever, night sweats, blood-stained sputum, and afternoon feverishness are common, and weight loss is also a common occurrence. Different forms of tuberculosis have different clinical symptoms. Tuberculosis can be cured if it is identified early and treated promptly and properly with anti-tuberculosis therapy, allowing many to recover completely.
