[Surveillance of endemic situation of schistosomiasis in a national surveillance site in Honghu City from 2005 to 2013].
OBJECTIVE
To understand the dynamics of schistosomiasis japonica in a national surveillance site in Honghu City, Hubei Province, China, so as to provide the evidence for formulating the intervention strategy of schistosomiasis control in the whole city.


METHODS
The surveillance was performed in the surveillance village according to The National Surveillance Scheme of Schistosomiasis Japonica, and the results were analyzed statistically from 2005 to 2013.


RESULTS
The schistosome infection rates in residents and cattle decreased from 1.76% and 20.93% in 2005 to 0 in 2013, respectively. The density of living Oncomelania snails decreased from 4.20/0.1m2 to 0.17/0.1m2, respectively. No infected snails were found during the period of 9 years in succession. The total area of snail control with molluscicidal drugs was 68.38 hm2 in the monitoring sites during the period of 9 years, and the expanded chemotherapy was performed for 634 person-times. Sixteen (person-time) advanced schistosomiasis patients received the treatment and salvation. The health education was carried out in 3 836 (person-times) students. Totally 5 685 leaflets of health education were distributed, and 17 bulletin boards of health education were performed. Five warning boards were set up at the environments with snails.


CONCLUSIONS
The transmission of schistosomiasis in the surveillance site in Honghu City shows a gradually decreasing trend year by year. However, the surveillance and control of snails still should be strengthened.
