Tuberculosis can actually be completely cured, primarily through anti-tuberculosis treatment. If it is confirmed to be active tuberculosis, systematic and standardized anti-tuberculosis treatment is required. Through scientific and reasonable anti-tuberculosis treatment and taking medication on time and according to guidelines, most tuberculosis patients can be cured, with a cure rate reaching 85%. The treatment includes an intensive phase of anti-tuberculosis treatment and a consolidation phase, with the total course of treatment being about six months. After being cured, it is not easy to relapse, but it is essential to take medications on time, adjust nutrition, modify work and rest schedules, and rest well.

How is tuberculosis treated?

The primary treatment for tuberculosis is still chemotherapy, also simply called chemo, but the chemotherapy for tuberculosis is completely different from the anti-tumor chemotherapy we talk about in cancer, and the medications are also completely different. There are about more than ten anti-tuberculosis drugs, which can be divided into first-line and second-line drugs, and currently, there are third-line drugs under research. Chemotherapy for patients with pulmonary tuberculosis should be started early and administered in combination. The types of combined medication for patients with pulmonary tuberculosis generally involve three or more drugs. Some patients may exhibit drug resistance or intolerance to some drugs' side effects, and thus, second-line drugs may be used. Additionally, some patients, due to special conditions, may require four or five types of anti-tuberculosis drugs. It is crucial to strictly follow medical advice regarding how to medicate and treat. Furthermore, patients with pulmonary tuberculosis must ensure complete medication adherence, as the treatment duration for tuberculosis is quite long, typically requiring at least six months, and some patients may need one or even two years. Regular medication intake is very important because some patients might experience symptoms like coughing up blood or others, such as those with pleurisy, who might develop pleural effusion. Therefore, treatments targeted at other symptoms are necessary. Patients who cough up blood might need hemostatic drugs, while those with severe hemoptysis may even require interventional surgery. Some with tuberculous pleurisy might need to have pleural effusion drained. Additionally, some patients with pulmonary tuberculosis might experience adverse reactions to medications, such as liver or kidney failure, visual impairment, or numbness in the hands, which would require adjustments to their medication or changes based on their complications. Treatment should also be targeted toward these adverse reactions.

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.

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.

Is tuberculosis serious?

Tuberculosis is a relatively serious disease, but if it is treated and managed promptly in the early stages, it often can be brought under control and most cases can completely recover. If the disease is allowed to progress unchecked, it can develop from ordinary tuberculosis into an especially severe form of the disease, even endangering life and leading to extrapulmonary tuberculosis. The severity of tuberculosis depends largely on the extent of damage to the lungs and whether there is extrapulmonary tuberculosis. Once tuberculosis is confirmed, scientifically sound and appropriate anti-tuberculosis treatment should be undertaken.

Is tuberculosis easily contagious?

Whether tuberculosis (TB) is easily transmitted primarily depends on the source of infection, which refers to the TB patients and the amount of Mycobacterium tuberculosis in their sputum. If TB bacilli can be detected in their sputum, and the quantity is substantial, then their infectiousness is indeed higher. However, if the TB patient has undergone treatment, or if there are only a few TB bacilli in their sputum, or none at all, then their infectiousness may not be as significant. The second factor is the mode of transmission, which mainly occurs through the respiratory tract. If TB patients can be isolated timely, or if they wear masks, and their sputum is properly managed, for example by wrapping the sputum in paper and burning it, then they are less likely to transmit the disease to others. TB generally involves susceptibility issues; even if someone has been vaccinated with BCG or the TB vaccine, they can still be reinfected. Therefore, controlling these three transmission pathways is essential to minimize the risk of contracting TB.
