<p><b>OBJECTIVE</b>To understand epidemiological features of pulmonary tuberculosis in urban Giangzhou and tendency of its registered cases.</p><p><b>METHODS</b>Registered data of pulmonary tuberculosis cases in urban Guangzhou during 1994 to 2000 were collected and analyzed comprehensively with method of descriptive epidemiology.</p><p><b>RESULTS</b>Incidence 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.</p><p><b>CONCLUSIONS</b>It is necessary to keep in minds that highly prevalent area was extended from tuberculous epidemics.
