Tuberculosis can be cured if it is detected early and treated promptly with standard anti-tuberculosis therapy, resulting in a very good prognosis. However, it is very unfortunate if detection is delayed or if standard treatment is not administered, as the tuberculosis may recur or infect with drug-resistant strains, causing permanent damage to lung function. Advanced pulmonary lesions or significant hemoptysis can be life-threatening. Currently, the treatment of tuberculosis involves chemotherapy, with principles including early treatment, combination therapy, appropriate dosing, regularity, and completeness, usually lasting at least six months. Common first-line anti-tuberculosis medications include isoniazid, rifampin, ethambutol, and pyrazinamide. Initially, a two-month intensive phase of treatment with isoniazid, rifampin, ethambutol, and pyrazinamide is followed by a four-month continuation phase with isoniazid and rifampin. During the treatment of tuberculosis, it is important to enhance one's resistance and immune function and to improve nutrition to facilitate recovery. (Use medications under the guidance of a doctor.)

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.

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.

How is tuberculosis diagnosed?

The diagnosis of tuberculosis primarily involves combining relevant clinical symptoms, such as whether there is cough, expectoration, low fever, night sweats, and blood in phlegm. It also requires considering the patient's chest imaging features, whether there is obvious infection, fresh exudation, cavities, as well as sputum tests. For example, if the sputum stain for acid-fast bacilli is positive, and the sputum culture is positive, using these comprehensive diagnostic methods, tuberculosis can be diagnosed, after which anti-tuberculosis treatment should be initiated.

Does tuberculosis cause headaches in its initial stage?

Tuberculosis is a highly contagious respiratory disease caused by the infection of Mycobacterium tuberculosis in the lungs, generally transmitted through respiratory droplets or direct contact. When infected with tuberculosis, symptoms that often appear include low-grade fever in the afternoons, coughing, expectoration, hemoptysis, chest pain, chest tightness, and shortness of breath. Some may experience weight loss, fatigue, and night sweats. Therefore, when patients with pulmonary tuberculosis exhibit an afternoon low-grade fever, it often leads to the occurrence of headaches. Therefore, it is very common for patients in the early stages of pulmonary tuberculosis to exhibit various symptoms, primarily due to the rise in body temperature.

How is tuberculosis transmitted?

How is pulmonary tuberculosis transmitted? First, we need to know the pathogen of pulmonary tuberculosis, which is the tuberculosis bacillus. Tuberculosis bacillus is a type of bacterium that can live in our surrounding environment. Pulmonary tuberculosis also needs a source of infection, that is, a patient carrying the tuberculosis bacillus. The most common source of tuberculosis infection is usually patients with secondary pulmonary tuberculosis. Then, its mode of transmission mainly includes coughing, sneezing, laughing, and talking loudly, which can release the tuberculosis bacilli from the patient into the air, spreading them through droplets. Droplet transmission is the most important route for the spread of pulmonary tuberculosis. Additionally, pulmonary tuberculosis can also be transmitted through other routes such as the gastrointestinal tract or the skin, although these methods of transmission are less common.
