[Effect evaluation of transmission control of schistosomiasis in 14 counties (cities, districts) of Jiangsu Province].

Abstract

OBJECTIVE

To assess the control effect of transmission control of schistosomiasis in 14 counties (cities, districts) of Jiangsu Province.

METHODS

According to the requirement of the national assessment scheme of schistosomiasis, the effect of schistosomiasis control was evaluated. The schistosomiasis morbidity and changes in Oncomelania snail status in recent 2 years were assessed. The field survey was done by using the stratified sampling method. A heavy-endemicity administrative village was randomly sampled from the townships with low, moderate and heavy endemicities in each county, respectively as the assessment villages. The morbidity in resident populations and free-grazing domestic animals and the snail infections in the settings where snails were detected and frequent human and domestic animal activities were observed in recent 3 years.

RESULTS

During the period from 2007 through 2010, the transmission control effect of schistosomiasis was assessed in 14 counties (cities, districts) of Jiangsu Province, and field surveys were performed in 42 villages of 39 townships. A total of 264 settings, 1 679.73 hm2 and 39 894 frames were surveyed, and 2 179 snails were collected. Of the 405 living snails dissected, no infected snails were detected, and the snail infection rate was 0. Totally 22 147 residents were investigated. The serum examination of schistosome infection was performed in 22 147 residents, and 300 were sero-positive, with a sero-positive rate of 1.35% (0.30%-4.26%). The stool examination was done in 297 sero-positive cases, and no cases were stool-positive, with a stool-positive rate of 0. A total of 2 931 domestic animals were investigated, including 230 head of cattle, 2 333 pigs and 368 sheep, and no infections were detected. The files regarding the schistosomiasis morbidity and snail status have been established in 14 counties (cities, districts). All infected snails were killed in the 14 counties (districts, cities) 2 years prior to the assessment, and the mean time that no infected snails were detected was 2.71 years (2-4 years). No acute schistosomiasis patients were found in all 14 counties (districts, cities) more than 3 years prior to the assessment.

CONCLUSION

According to the Criteria for Control and Elimination of Schistosomiasis in China (GB 15976-2006), the transmission of schistosomiasis in 14 countries (cities, districts) of Jiangsu Province has been controlled.
