RESUMO
Objective: To understand the endemic status of echinococcosis in Xinjiang Uygur Autonomous Region, to provide scientific basis for planning and promoting control measures in this region. Methods Eight hundred people of all age ranges were examined in each of the selected agricultural area, pastoral area, pastoral-agricultural area, and township area of 92 counties in 14 prefectures in Xinjiang during March and October of 2012, resulting in a total of 3 200 people surveyed in each county. B ultrasonic abdominal scan was performed, accompanied by serum antibody detection for suspected cases. Methods: Eight hundred people of all age ranges were examined in each of the selected agricultural area, pastoral area, pastoral-agricultural area, and township area of 92 counties in 14 prefectures in Xinjiang during March and October of 2012, resulting in a total of 3 200 people surveyed in each county. B ultrasonic abdominal scan was performed, accompanied by serum antibody detection for suspected cases. Results: A total of 293 140 people were examined. The overall morbidity was 0.14%ï¼407/293 140ï¼. The morbidity in the north region was 0.18%ï¼290/158 985, 71.25%of all the casesï¼, and that in the south region was 0.09%ï¼117/134 155, 28.75% of all the casesï¼ï¼P<0.05 between the regionsï¼. The cases were mainly distributed in Urumqi Cityï¼19.90%, 81/407ï¼, Tarbagatai Prefectureï¼13.27%, 54/407ï¼, Yili Kazak Autonomous Prefectureï¼13.02%, 53/407ï¼ and Changji Hui Autonomous Prefectureï¼9.83%, 40/407ï¼. The prevalence was higher in Mongolianï¼»0.42%ï¼21/5 045ï¼ï¼½ and Kirgiz ï¼»0.35%ï¼32/9 045ï¼ï¼½ than in other ethnic groupsï¼0.07%-0.22%ï¼ï¼P<0.05ï¼. There was no significant difference in prevalence between malesï¼»0.13%ï¼195/144 715ï¼ï¼½ and femalesï¼»0.14%ï¼212/148 425ï¼ï¼½ ï¼P>0.05ï¼. The prevalence was lowest in the 0-9 year groupï¼»0.07%ï¼7/10 754ï¼ï¼½, and higher in the the age groups of 70-79ï¼»0.27%ï¼33/12 310ï¼ï¼½ and 80-99 yearsï¼»0.28%ï¼7/2 461ï¼ï¼½, showing a trend of elevation with ageing. Further, the cases were mainly in the population of 30-49 yearsï¼43%, 175/407ï¼. The prevalence was higher in the uneducatedï¼»0.25%, 39/15 470ï¼½ than in the educated populationsï¼0.06%-0.14%ï¼ï¼Pï¼0.05ï¼, and higher in pastoralistsï¼»0.29%, 63/22 074ï¼½ than in populations with other occupationsï¼0.00%-0.13%ï¼ï¼P<0.05ï¼. The prevalence in pastoral area, agricultural area, pastoral-agricultural area, and township area was 0.16%ï¼70/44 247ï¼, 0.16%ï¼181/113 016ï¼, 0.12%ï¼88/70 610ï¼ and 0.10%ï¼68/65 267ï¼, respectively. The township area had the lowest prevalence, which was significantly different from both the pastoral area and the agricultural area (P<0.05). Conclusion: Echincoccosis is widely distributed in Xinjiang, with more cases in the north.
