DAR ES SALAAM, Oct. 27 (Xinhua) -- A Chinese public health expert team under the China-aided Zanzibar schistosomiasis control project on Sunday completed Zanzibar's first-ever distribution map of schistosomiasis transmission vectors, marking a significant step in the efforts of Tanzania's island region to eliminate the disease.
The achievement follows a month-long systematic survey of Biomphalaria snails, the intermediate hosts of schistosoma mansoni, across 320 key water bodies on the islands, according to Wang Wei, the team leader.
