[Evaluation of transmission control of schistosomiasis in 19 counties (cities, districts) of Hubei Province in 2013].

OBJECTIVE

To evaluate the schistosomiasis transmission control in 19 counties (cities, districts) of Hubei Province in 2013.

METHODS

The epidemic villages from different counties were randomly sampled by the cluster sampling method as the evaluation villages. The schistosome infection status of human and livestock, the Oncomelania hupensis snail status, the documents and data of schistosomiasis control, acute infection control and health education were investigated in the field.

RESULTS

The serum examination of schistosome infection was performed to 29 631 residents, and 2 068 were positive, with a positive rate of 6.98% (0.78% -16.47%). The stool examination was performed to 2 021 sero-positive persons, and 47 cases were stool-positive, with an infection rate of 0.16% (0 - 0.82%). The cattle was the main domestic animals in 19 counties (cities, districts), and the measures of replacing cattle with machine for cultivation were done in 17 counties (cities, districts). Totally 105 cattle in Caidian District and Huangpi District received stool examinations and no positives were detected. A total of 1 579.37 hm2 and 31 829 frames in 154 environments were surveyed, and 4 857 snails were collected. Of the 1 935 living snails dissected, no infected snails were detected. The files regarding the schistosomiasis morbidity and snail status have been established in 19 counties (cities, districts) since 2009.

CONCLUSIONS

The transmission of schistosomiasis in 19 counties (cities, districts) of Hubei Province has reached the standard of transmission controlled.
