ABSTRACT
Objective To determine the coverage of gonorrhea and syphilis case reporting in China,and provide information for managing STD case-reporting,investigating under-reporting and evaluating STD epidemic.Methods The gonorrhea and syphilis case-reporting data from 31 provinces in 2005 were collected with systematic sampling by months of February,May,August and November through National Information System for Disease Control and Prevention,and the coverage of the casereporting by county category in 31 provinces were analyzed.Results The average coverage of gonorrhea case-reporting were 56.66%,66.33%,68.90% and 68.27% in February,May,August and November in 2005,respectively,while the average coverage of syphilis were 42.61%,55.56%,59.46% and 60.59% in these months,respectively.The coverage of case reporting in developed or southeast ern areas,such as Shanghai,Beijing,Tianjin,Chongqi,Zhejiang,Jiangsu,Guangdong,Guangxi,Hainan,and Fujian provinces was higher by more than 80%.However,the coverage in economically less-developed or west ern areas,including.Hebei,Shanxi,Inner Mongolia,Shaanxi,Gansu,Yunnan,Guizhou,Qinghai and Tibet provinces,was lower by less than 50%.Conclusions Overall,the coverage of gonorrhea and syphilis case reporting in the country is relatively low,which directly compromises the accuracy of STD case reporting data.It is suggested that management,surveillance and evaluation of STD case reporting should be strengthened,especially in economically less-developed or western areas.
