Abstract
OBJECTIVES: To find out the epidemiological characteristics of extrapulmonary tuberculosis (TB) in Shanghai, and to explore value of this surveillance. METHODS: Distribution of extrapulmonary TB for sex, age and suffering site 1996-1999 were analyzed. In addition, its incidence trend and mortality were also investigated. All registered cases from ten urban districts of Shanghai were included. RESULTS: The new registration rates of extrapulmonary TB 1996-1999 were 4.65-5.78/100,000. The proportion of extrapulmonary TB to all TB was 9.7%-11.8%. The extrapulmonary TB accounted for 14.1%-17.6% of all death due to TB. The rankings of extrapulmonary TB were as follows: lymph node TB (38.3%), bone and joint TB (19.9%), urinary and genital TB (16.7%), intestine and peritoneum TB (9.1%), cerebral and nervous TB (6.4%). The sex ratio of male to female was 1 to 1.35. The new registration rates of extrapulmonary TB increased with age except that of cerebral and nervous TB was the highest in middle and young age group. CONCLUSIONS: Surveillance on extrapulmonary TB is an important part of TB surveillance, with significant value for TB control.
