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.

Symptoms of pulmonary tuberculosis

Now let me talk about the symptoms of tuberculosis. Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis, which can invade many organs, with pulmonary tuberculosis being the most common. The main symptoms are respiratory symptoms and systemic symptoms. The respiratory symptoms are mainly manifested as coughing, expectoration for more than two weeks, or blood in the sputum, which are common suspicious symptoms of pulmonary tuberculosis. Generally, the cough is mild, either dry or with a small amount of mucus. When cavities form, the amount of sputum may increase, and if there is a secondary bacterial infection, the sputum may become purulent. If there is concomitant bronchial tuberculosis, it will manifest as an irritating cough. About one-third of patients will experience hemoptysis, and some may experience massive hemoptysis. If the tuberculosis lesions involve the pleura, it can manifest as chest pain. Dyspnea is more common in patients with caseous pneumonia or those with a large amount of pleural effusion. These are local symptoms. Systemic symptoms mainly manifest as fever, which is the most common manifestation, often as long-term afternoon fever, meaning it begins to rise in the afternoon or evening, drops in the morning, and then returns to normal. Some patients may also experience fatigue, night sweats, loss of appetite, weight loss, etc. Women of childbearing age may experience menstrual disorders, etc.

What is tuberculosis?

Tuberculosis is a disease where the bacterium Mycobacterium tuberculosis infects the lungs. It is a persistent bacterium that grows slowly. Tuberculosis is an infectious disease and quite common historically, often referred to as consumption in the past, as mentioned in the novels of Lu Xun. In modern times, tuberculosis is relatively manageable if the infection has not developed resistance to drugs. Proper anti-tuberculosis treatment can result in a cure rate exceeding 90% on the first attempt. However, if the treatment is not adhered to correctly—if the patient stops taking the medication prematurely or does not follow the prescribed regimen—the bacteria may develop resistance, reducing the effectiveness of the treatment. This is particularly problematic in elderly patients, who might also experience adverse reactions to tuberculosis medications, making treatment difficult. Thus, while tuberculosis is generally treatable, infections with drug-resistant strains can be fatal if not managed properly.

Does tuberculosis get inherited?

Is tuberculosis hereditary? Tuberculosis is not a hereditary disease; it is an infectious disease. Infectious diseases and hereditary diseases are two completely different concepts. Tuberculosis is generally infectious, which means that in a family, if parents are infected, they can easily transmit the tuberculosis bacteria to their children or others around them. Therefore, many people might mistakenly believe that tuberculosis is hereditary. However, this is not the case; tuberculosis is transmitted through the tuberculosis bacteria.

Can tuberculosis be cured completely?

Whether tuberculosis can be completely cured varies from person to person. Most cases of tuberculosis, especially initial occurrences of pulmonary tuberculosis, can be cured in more than 80 to 90 percent of patients if they undergo standardized anti-tuberculosis treatment. However, it is essential that the treatment is standardized; it is not appropriate to simply take medication for one or two months and then stop when symptoms seem to disappear. The treatment duration for pulmonary tuberculosis is considered to be at least six months, and for some patients, it may even extend to a year. However, not all cases of pulmonary tuberculosis can be completely cured. A small percentage of patients may not achieve complete eradication due to resistance to tuberculosis bacteria or intolerance to the side effects of tuberculosis medications. In such cases, the prognosis might be poor, and some individuals may succumb to tuberculosis due to these factors.
