Tuberculosis is a chronic infectious disease that seriously endangers human health. Although the prevalence of tuberculosis in China has improved greatly with the prevention and treatment efforts, the incidence of tuberculosis is still high, especially among children, young people and the elderly. According to statistics, there are still about 6 million active TB patients in China. Of these, l million are still the source of infection. Nearly 300,000 people die each year. It is significantly higher than that of developed countries. The cause of tuberculosis is clear, there are measures for prevention and treatment. The key to treatment lies in formal treatment. Adherence to formal treatment 80% to 95% of patients can be cured. And some cases of treatment failure are mostly related to the failure to adhere to formal treatment. The formal treatment of tuberculosis, in the final analysis, is to adhere to the “early, joint, appropriate, regular, the whole” cross policy. ”Early” refers to the need to seek medical attention and early treatment for tuberculosis. Because early exudative lesions of tuberculosis can be absorbed after treatment, but late lesions are difficult to be completely cured. ”Combination” refers to the combination of two or more anti-tuberculosis drugs in treatment to reduce the development of bacterial resistance. We know that when the tuberculosis bacteria develop drug resistance, the original treatment will fail, and it is very easy to develop drug resistance with one drug alone. We stipulate that 4 anti-tuberculosis drugs such as rifampicin and isoniazid should be combined in the beginning stage, and after 2 months, the treatment is changed to 2 drugs such as rifampicin and isoniazid. The total duration is 6-9 months. The term “appropriate dose” means that the dosage of drugs should be appropriate. Insufficient dosage makes the treatment ineffective and also easy to develop bacterial resistance. Excessive dosage is likely to produce toxic side effects. ”Regularity” refers to strict adherence to the number of doses and intervals determined by the treatment plan to avoid omissions and interruptions. The “full course” refers to the course of treatment should be sufficient, currently using a short course of treatment of 6-9 months, do not stop the drug too early to avoid incomplete treatment or relapse. Please remember, to recover early, we must adhere to the regular treatment.
