For tuberculosis, you can visit the Department of Infectious Diseases. Infectious diseases or respiratory medicine are suitable options, and if a hospital doesn't have these specialized departments, you can consider visiting the Center for Disease Control. In smaller hospitals, below the secondary level, where such specific departments may not be available, you might also consider seeing the Department of General Internal Medicine. General Internal Medicine or typical internal medicine departments can also handle this. However, our first recommendation would still be the Respiratory Medicine Department. Some hospitals combine Infectious Diseases with other related departments, making them the preferred choice for tuberculosis patients as these departments likely have the most experience in treating such diseases.

Does tuberculosis cause a runny nose?

Do patients with tuberculosis have a runny nose? First, we need to understand what tuberculosis is. The pathogen of tuberculosis is Mycobacterium tuberculosis, commonly referred to as TB bacillus. Its primary site of infection is the lungs, but now we also classify and manage tracheobronchial and tuberculous pleurisy under pulmonary tuberculosis. However, these sites do not include the nasal part. Generally, patients with pulmonary tuberculosis show symptoms of the respiratory system and systemic symptoms. The most common respiratory symptoms include coughing and phlegm production for more than two weeks. Some patients may also experience hemoptysis, with varying amounts from mild to severe. A few patients may also experience chest pain. Additionally, patients with caseous pneumonia or significant pleural effusion may experience difficulty in breathing. Systemic symptoms of tuberculosis include fever, mainly characterized by afternoon tidal fever, with some patients exhibiting high fevers, and other general symptoms such as loss of appetite, weight loss, night sweats, and fatigue. However, the majority of patients with pulmonary tuberculosis do not exhibit nasal symptoms, meaning a runny nose is generally not a manifestation of tuberculosis. It could be possible that a tuberculosis patient might also have other infections or causative diseases, such as allergic rhinitis.

Local symptoms of pulmonary tuberculosis

The local symptoms of tuberculosis primarily require us to understand where tuberculosis occurs. Currently, tuberculosis in the lung tissues, trachea, bronchi, and pleura are all classified as pulmonary tuberculosis. The primary local symptoms are still respiratory symptoms, with the most common being cough and expectoration. Patients with tuberculosis generally have a slow onset, with most experiencing cough and expectoration that can persist for two weeks or more. Some patients may also exhibit symptoms like blood in the sputum or hemoptysis. Additionally, some patients may experience other symptoms; for example, those with pleural involvement might have irritative cough, chest pain, and difficulty breathing, while those with tracheobronchial involvement might exhibit a prolonged irritative cough. Some patients may also develop bronchial stenosis, which can lead to difficulty breathing.

Does the BCG vaccine prevent tuberculosis?

The BCG vaccine primarily prevents infection by the tuberculosis bacillus, so it can prevent pulmonary tuberculosis. The protective effect of the BCG vaccine is mainly achieved through inducing a cell-mediated immune response. After vaccination, a primary infection is formed, which is processed by macrophages that transmit the antigen information to immune-active cells, leading to the differentiation and proliferation of T cells and the formation of sensitized lymphocytes. When the body is re-infected with the tuberculosis bacillus, the macrophages and sensitized lymphocytes are activated, causing a specific immune response in the body, thereby resisting the infection by the tuberculosis bacillus. Therefore, the BCG vaccine mainly prevents pulmonary tuberculosis.

Does tuberculosis infect people?

Tuberculosis is a contagious disease, and hearing the term "tuberculosis" inevitably makes people nervous. However, not all tuberculosis patients are contagious. Research shows that among tuberculosis patients, only those who have tuberculosis bacteria found in sputum smear tests are contagious. With a source of infection, the tuberculosis bacteria must be transmitted to others through certain routes. Airborne transmission is the main route of transmission for tuberculosis bacteria. When a tuberculosis patient coughs, sneezes, or speaks loudly, they release a large number of droplet nuclei containing tuberculosis bacteria into the air, which can be inhaled by healthy individuals and cause infection. The degree of tuberculosis bacteria infection mainly depends on factors such as the amount of bacteria the patient expels, the severity of coughing symptoms, and the extent of contact. Therefore, when there is a tuberculosis patient nearby, we first need to understand whether they are in the active phase of the disease, that is, expelling bacteria, and whether they are undergoing anti-tuberculosis chemotherapy. If the patient has a negative sputum test or has undergone chemotherapy for a positive sputum test, such patients have very low contagiousness, so there is no need to worry too much about being infected.

Does tuberculosis cause fever in its initial stage?

Tuberculosis is caused by an infection of the lungs by the bacterium Mycobacterium tuberculosis, and it is a very common infectious respiratory disease clinically. Typically, the early stage of tuberculosis is accompanied by mild fever to varying degrees, usually occurring in the afternoon, along with coughing, expectoration of blood, chest tightness, shortness of breath, and even chest pain, weight loss, fatigue, and night sweats as accompanying clinical symptoms. In the early stages, the diagnosis of tuberculosis in patients is generally made through these specific clinical symptoms, along with some sputum culture and chest X-ray examinations. Usually, most patients with early-stage tuberculosis will experience symptoms of low-grade fever, but these patients have a characteristic of fever that occurs in the afternoon and does not require antipyretics as it can return to normal by itself in the evening.
