Early detection and appropriate anti-tuberculosis treatment of tuberculosis can lead to a normal lifespan once cured. However, it is important to exercise regularly and enhance immunity, since tuberculosis may recur if the body's resistance decreases. With the increase of drug-resistant tuberculosis, treatment difficulties have intensified. If it is detected late or not treated properly and the lung damage progresses to an advanced stage, it can be life-threatening, with survival ranging from days to years. When tuberculosis involves massive hemoptysis, death can occur at any time due to suffocation or hemorrhagic shock, depending on the specific condition.

What department should tuberculosis patients visit?

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.

Can people with tuberculosis drink alcohol?

Whether patients with tuberculosis can drink alcohol, first of all, it is important to know that tuberculosis is a chronic infectious disease and a consumptive disease that consumes the body's calories. Drinking alcohol can affect the body's absorption of energy. Moreover, most patients with tuberculosis need to take anti-tuberculosis medication, most of which are metabolized through the liver and can cause varying degrees of liver damage. Drinking alcohol can exacerbate liver damage and reduce the effectiveness of the medication. Additionally, since there are many types of anti-tuberculosis medications for tuberculosis patients, some medications may cause adverse reactions when drinking alcohol. Therefore, all tuberculosis patients must strictly abstain from drinking alcohol during treatment.

Does early-stage pulmonary tuberculosis cause fever?

Early stage tuberculosis patients generally exhibit clinical symptoms such as fever, primarily low-grade fever in the afternoon, along with coughing, hemoptysis, chest pain, chest tightness, and additional symptoms like weight loss, fatigue, and night sweats. These are very common and typical clinical symptoms of tuberculosis. Therefore, fever is very common in the early stages of tuberculosis. Consequently, once tuberculosis is accurately diagnosed in patients, it is crucial to promptly administer antitubercular drugs for systematic treatment. Usually, with a treatment duration of 6-9 months, the symptoms of early-stage tuberculosis and fever can be effectively controlled.

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.
