The Epidemic Survey And Analysis Of Tuberculosis In Shanxi Province

Objective: To investigate the influence rate, the prevalenceof tuberculosis and drug resistance tuberculosis in Shanxi province. To evaluate the efficacy of control measures from 1990 to 2000 and to provide scientific basis for making Shanxi Tuberculosis Control Programmer from 2001 to 2010.Methods: 30831 persons in 21 places of 11 cities in Shanxihave been investigated . Tuberculin testing was carried out among 0-44 years old children; fluroscopy was carried out for >15 years old population and children with >10mm reaction of tuberculin testing; chest X-ray film, sputum smear and culture were done for the patients of fluroscopy abnormal and suspects of tuberculosis symptom(persistent cough for 3 weeks or more);drug sensitivity test was done for the patients with culture positive; a retrospective study of tuberculosis mortality in 1999 was conducted at all investigation points; social economic study was done for the active pulmonary tuberculosis cases; the survey of tuberculosis infection rate for all population was carried out in 2 investigation points. The analysis was done with SAS Software package.Results: Among 30831 persons at 21 places of 11 cities, 146active pulmonary tuberculosis, 46 smear positive pulmonary tuberculosis, 56 culture positive pulmonary tuberculosis have been diagnosed, the prevalence of active pulmonary tuberculosis was 474 per 100 000,the prevalence of smear positive pulmonary tuberculosis was 149 per 100 000 and the prevalence of bacteriological positive pulmonary tuberculosis was 182 per 100 000,it would increase when ages increase .It calculates accordingly that there are 147572 active pulmonary tuberculosis in our province at present, with 46398 case transmission . Compared with the epidemiological results of the year 1990(444 per 100 000 , 132 per 100 000), prevalence of pulmonary tuberculosis and that of smear positive have some increase. There is some differences (P<0. 05) between male' s and female ' s at the prevalence of active pulmonary tuberculosis, and there is no difference (P>0. 05) between male' s and female' s smear positive pulmonary tuberculosis . The young got it easily, the old are the main source of influence. The prevalence of tuberculosis and smear positive pulmonary tuberculosis are higher in countries (501 per 100 000, 164 per 100 000) than those in cities (351 per 100 000, 0 per 100 000) obviously, exudative tuberculosis is still a main kind, most of the patients are out of management, drug resistance tuberculosis especially the proportion of acquired drug resistance tuberculosis was still high.Conclusions: The epidemic situation of tuberculosis is veryserious in our province, it's the main element influence of epidemic situation to find and manage the patients. Point out: The governments at different levels must pay more attention to tuberculosis control programme ,increase the budget , strengthen law management, finding early, diagnose early and have good management are very important for decreasing the epidemic situation.
