Epidemiological investigations on echinococcosis in Akto County, Xinjiang
Objective To conduct an epidemiological investigation on echinococcosis in Akto County,Xinjiang for understanding the prevalence and characteristics of the disease,so as to provide evidence for prevention and treatment.Methods A total of 24 villages(4 villages in each town and 3 towns in agricultural and pasturing areas of Akto county respectively)were selected as investigation spots.The investigation on echinococcosis covered whole population while serum antibody against echinococcosis was detected in 6-12 years old students as well as the investigation on echinococcosis in livestock and dogs was conducted.B ultrasound scan of the abdomen was used to check the infection of the hydatid cyst.The ELISA method was used to detect the serum IgG antibody against echinococcosis among 6-12 years old students and the antibody in dog fecal samples.The organs such as liver,lung,kidney,spleen,heart and other organs and peritoneum of the slaughter livestock were examined through palpation and visual observation for the infection rate of the hydatid cyst.Results In agricultural and pasturing regions,a total of 6 113 people was investigated.Only one patient with hydatid disease was found at Carkeqike Town in pasturing region with a proportion of 0.02％(1/6 113)and a prevalence rate of 0.49/100 000(1/202.3 thousand).The positive rate of echinococcosis serum antibodies among 6-12 years old students in agricultural areas and pastoral areas was 2.70％(49/1 813)and it was 2.24％(211938)in pasturing areas and 3.20％(28/875)in agricultural areas without statistical significance(X2=1.54,P＞0.05).Moreover,the positive rate in female was 4.17％(30/720),higher than that in male(1.74％,19/1 093)(X2=9.73,P＜0.05),and the difference between the positive rate in pastoral areas(2.24％,21/938)and that in agricultural area(3.20％,28/875)was not statistically significant(X2=1.54,P＞0.05).The positive rate of female in pasturing areas(3.77％,13/345)was higher than that of man(1.35％,8/593)(X2=5.83,P＜0.05),and the difference of positive rate between male 2.20％(11/500)and female 4.53％(17/375)was not statistically significant(X2=3.76,P＞0.05)in agricultural areas;and the positive rate of male 1.35％(8/593)was less than that of female 3.77％(13/345)(X2=5.83,P＜0.05)in pasturing areas.The positive rates between 6-12 age groups was not statistically significant(X2=0.20-2.20,P＞0.05).The carrying rate of hydatid cyst in sheep was 5.25％(49/933),and it was 1.29％(4/311)in bovine.The positive rate of echinococcosis antibody in stool samples of domestic dogs was 0.46％(9/1 967),and the difference of positive rate between the agriculture areas and pasturing region was not statistically significatant(X2=0.01,P＞0.05).Conclusion The major population of echinococcosis patients is young adult in Akto County.The positive rate of echinococcosis antibody in sera of 6-12 years old students and in stool samples of domestic dogs did not exhibit any difference.The infection rate was higher in female of agricultural areas.Therefore,the management of domestic dogs should be strengthened,the awareness of preventing the disease must be improved in people so as to effectively reduce the prevalence.
