[Effectiveness of integrated schistosomiasis control strategy in marshlands of Qixia District, Nanjing City].

OBJECTIVE

To evaluate the effectiveness of integrated schistosomiasis control strategy in marshlands of Qixia District from 2004 to 2013.

METHODS

The endemic situation and integrated control data of schistosomiasis in Qixia District from 2004 to 2013 were collected, and the morbidity and Oncomelania hupensis snail status before and after the implementa- tion of integrated schistosomiasis control strategy were compared.

RESULTS

Following 10-year integrated schistosomiasis control, the human schistosome infection rate gradually decreased in Qixia District, and no infection was detected since 2007. A gradual reduction was observed in the infection rate of domestic animals, and all bovine was eliminated from the regions along the Yangtze River since 2006. In addition, the snail area and the density of living snails in 2013 reduced by 42.25% and 82.56% as compared to those in 2004, and no infected snails were found since 2009. In 2010, the district achieved schistoso- miasis transmission control.

CONCLUSION

The integrated schistosomiasis control strategy is effective to accelerate schistoso- miasis control process and achieve the criteria of schistosomiasis transmission control rapidly.
