[Epidemiological analysis of extrapulmonary tuberculosis in Shanghai].
OBJECTIVE
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.
