Abstract:
OBJECTIVETo understand epidemiological features of pulmonary tuberculosis in urban Giangzhou and tendency of its registered cases.
METHODSRegistered data of pulmonary tuberculosis cases in urban Guangzhou during 1994 to 2000 were collected and analyzed comprehensively with method of descriptive epidemiology.
RESULTSIncidence of recently smear-positive registered rate (IRSPRR) increased from 16.68 per 100,000 in 1994 to 26.27 per 100,000 in 2000, with an average annual increase of 7.86%. The highest standardized IRSPRR was 33.70 per 100,000 in Fangcun District. Average IRSPRR was 30.50 per 100,000 in males and 11.60 per 100,000 in females. IRSPRR increased with age, with a peak of 61.22 per 100,000 at age over 70, double as that at age of 50 - 69. Recently smear-positive registered case of pulmonary tuberculosis was highest in unemployment population, reaching 2529, accounting for 35.12% of the total. And, smear-positive registered rate decreased from 8.37 per 100,000 to 5.34 per 100,000, with an average annual reduction of 6.96%. Mortality of pulmonary tuberculosis decreased from 6.84 per 100,000 to 4.41 per 100,000.
CONCLUSIONSIt is necessary to keep in minds that highly prevalent area was extended from tuberculous epidemics. It is possible that unemployment people would be fallen into high-risk population. Potential source of infection should be found out as soon as possible.
