Tuberculosis, commonly known as “consumption”, is a chronic respiratory infectious disease caused by the tuberculosis bacillus, which is mainly transmitted to others through droplets spewed out by the patient when coughing, sneezing, or speaking loudly, but only tuberculosis patients whose tuberculosis bacilli can be detected in the sputum are contagious. Not all people who come into contact with TB bacteria will become infected with TB bacteria or develop TB disease. Studies have shown that a single infectious TB patient can infect 10 to 15 people with TB bacteria in a year. Infection by the TB bacillus does not always result in disease; it only develops into TB when the body’s resistance is lowered. The lifetime probability of developing TB in a person infected with the TB bacteria is about 10 percent. The main symptoms of TB are respiratory symptoms such as cough, sputum, hemoptysis and chest tightness, and systemic symptoms such as afternoon fever, emaciation, night sweats, fatigue, and so on. Therefore, for those who cough, cough sputum for more than 3 weeks, by cough symptomatic treatment effect is poor, especially with sputum with blood, night sweats, afternoon fever or weight loss, we should be highly suspected of tuberculosis may be, it is recommended to professional tuberculosis prevention institutions to receive appropriate examination. If you have tuberculosis, you should go to a professional tuberculosis prevention organization to receive regular treatment and management. Tuberculosis treatment should pay attention to the following points: ① must pay attention to, to establish confidence and determination to overcome the disease, adhere to the treatment. ② Tuberculosis is a chronic disease, must comply with the “early, regular, full, appropriate amount, combined” cross treatment policy, listen to the professional tuberculosis prevention and treatment doctor’s instructions, complete the full course of treatment. (iii) Regularly go to the professional tuberculosis prevention and treatment organization to review and dispense the drugs. Anti-tuberculosis drugs have some toxic side effects, such as liver function damage, gastrointestinal discomfort, skin rash, visual impairment, joint pain, etc. When these effects occur, you should go to a professional tuberculosis control organization for follow-up in time. ⑤ TB was once called a “rich disease”, which means that you should pay attention to rest, have a happy mood, strengthen nutrition, and eat more high-protein foods to enhance immunity. If you stop taking the medication too soon, or don’t take the medication according to the regulations, or take and stop taking the medication, it will bring the possibility of relapse or the formation of drug-resistant tuberculosis, and then it will be too late for you to regret the recurrence of the disease, aggravation of the lesions, serious damage to the lungs, difficulty in treatment, and increase in costs. The most important measure to prevent the spread of tuberculosis is to detect and cure infectious tuberculosis patients as early as possible. The infectiousness of TB patients will gradually disappear 2 to 3 weeks after they start receiving regular drug treatment. People who are in close contact with infectious tuberculosis patients are at high risk of tuberculosis infection, and these people should pay attention to the following protective measures: wear a good mask when in contact with the patient, maintain indoor ventilation and environmental hygiene, exercise to enhance physical fitness, pay attention to rest, regular rise and fall, and strengthen nutrition, timely inoculation of newborn babies with BCG vaccine, and isolation of children under the age of 3 years from the patient. When symptoms of tuberculosis appear, the patient should go to a specialized prevention and treatment institution in time to receive the appropriate examination.
