OBJECTIVE: To understand the status of @entity8434 in Maqing County of Qinghai Province in order to facilitate @entity8434 control in this region. METHODS: Ultrasonic scanning and indirect hemagglutination assay were used to detect @entity281 in residents >1 year old, according to the @entity1 's Republic of China Health Industry Standard--Diagnostic Criteria for Hydatid Disease (WS257-2006). Meanwhile, ELISA was used o detect the Echinococcus antigen in @entity235 's feces collected in Youyun, Dangluo and Xiadawu townships. RESULTS: Ultrasonic scanning showed that the prevalence of hydatid disease in the residents was 7.4% (116/1 561), @entity66 5.3% (82/1 561), @entity66 2.2% (34/1 561). The serum positive rate in @entity1 population was 23.8%(307/1 288). Of the 82 cases of @entity66 , 23 cases (28.1%) had the hydatid cyst with a diameter of >10 cm. The prevalence in males and females in the county was 5.3% (40/753) and 9.4% (76/808), respectively (P<0.05). Among populations with different occupations, the highest prevalence of hydatid disease fell into houseworkers (11/61, 18.0%), monks (5/41, 12.2%) and herdsmen (84/758, 11.1%). Among the age groups, the groups of >60 years (24/132, 18.2%) and 30-40 years (31/302, 10.3%) had higher prevalence of hydatid disease. The three townships with the higher prevalence were Youyun (29/247, 11.7%), Changmahe (6/63, 9.5%) and Dangluo (54/645, 8.4%). Of the 199 samples of @entity235 's feces, 54 were positive for Echinococcus antigens (27.1%), with a positive rate of 40.4% (23/57) in Youyun towship, being significantly higher than in the other two (P<0.05). CONCLUSION: Maqin county is a co-endemic area of @entity8434 and @entity4281 . The prevalence is higher in females and those over 60 years-old.
