TB(tuberculosis) Prevention

Tuberculosis is a chronic infectious disease epidemic broader, prevention must be dealt with. The prevention of the spread of tuberculosis must be the following three aspects.
1. tuberculosis is the main source of infection of tuberculosis, especially smear-positive TB patients with early chemotherapy to accept reasonable, sputum TB grams in the short term to reduce, and even disappeared, almost 100 percent can be cured, so early Found that patients, particularly of positive, reasonable and timely given the chemotherapy is a modern anti-TB work of the central link. Early detection of patients is timely for the following groups and X-ray of bacteriological examination: a chronic cough, hemoptysis by antibiotic treatment is invalid; opening of tuberculosis patients around the contacts; node-positive children in the trial of family members; Factories and mines workers, especially in patients with silicosis; than regular TB epidemic in the crowd for chest X-ray examination, early detection of some asymptomatic patients.
Second, cut off infection channels. Mycobacterium tuberculosis, mainly through respiratory tract infection. Therefore ban spitting, the patient's sputum-positive bacteria, daily necessities and the things around to be disinfected and properly addressed, indoor UV radiation can be disinfected once a day or every other day, every two hours, the utensils should be used in patients with boiling Disinfection 10-15 minutes, bedding out日下exposure in 4-6 hours, sputum boxes of toilet available to 5% -10%-soaked two hours, it is advisable to smear spit on a piece of paper burned or 20% of bleaching powder solution bubble 6-8 hours.
Third, BCG vaccination, it is a non-pathogenic of the live vaccine, inoculated in the human body can not get infected with Mycobacterium tuberculosis on the specific immunity, the protection rate of about 80 percent. 5-10 years can be maintained, thus at the end after several years of negative tests are needed multiple cropping. Fresh immunization targets are not infected with tuberculosis, a guitar-test negative, the younger the better, generally within three months after the birth injection, mainly for newborns and infants, primary and middle school students and new entrants into the city's minority areas citizens, Node-negative test carried out vaccination and multiple cropping, a method of vaccination injections and skin within two scratches on the skin, better skin injection. BCG vaccination effect of the affirmative, especially children, including acute miliary tuberculosis and the TB incidence rate of meningitis as a clear reduction, but of BCG generated by the immunity is relative, should attach importance to other preventive measures.
