Abstract:

Objective  To analyze the situation of echinococcosis surgerical cases in Xinjiang Uygur Autonomous Region from 2005 to 2013.  Methods  The surgery cases of echinococcosis in Xinjiang from 2005 to 2013 were collected， and analyzed with SPSS 17.0 and Epi Info 3.5.3 software.  Results  A total of 8 639 hydatid disease cases were reported during 2005-2013 from 94 counties （cities and districts） of 14 prefectures （municipalities） in the Region. The average number of annual operation cases were 960 cases（8 639/9 years）， and the annual incidence was 4.40/100 000 （960/21.81 million）. 82.8% （7 152/8 639） of report cases came from northern Xinjiang area with an incidence of 7.59/100 000， and 17.2% （1 487/8 639） distributed in southern Xinjiang area with an incidence of 1.58/100 000. There were 373 cases （4.4%， 373/8 639） reported in 2005， and increased to 1 434 cases （16.5% 1 434/8 639） in 2013（P＜0.05）. The cases mainly distributed in Yili Kazak Autonomous Prefecture （2 028 cases）， Tarbagatai Prefecture （1 218 cases）， Changji Hui Autonomous Prefecture （1 179 cases）， and Urumqi City （1 128 cases） of the northern Xinjiang area. There were 4 557 male （52.8%， 4 557/8 639） and 4 082 famale patients （47.3%， 4 082/8 639）（P＜0.05）. The age distribution showed a single-peak curve， and more patients concentrated in the age group of 31-40 years， accounting for 26.2% （2 265/8 639）. Among 8 639 cases， farmers accounted for 47.9% （4 134/8 639）.  Conclusion  The number of surgical cases of echinococcosis increases every year in Xinjiang since 2005， and the distribution of the disease shows a trend from the agricultural and pastoral areas to the towns.
