Objective To ascertain the status of human infection with hydatidosis in Gannan Tibetan Autonomous Prefecture, Gansu Province. Methods Both B ultrasound and dot-immunogold filtration assay （DIGFA） were used to examine subjects. Results Out of 1 040 subjects, 23 （2.21%） were infected with cystic echinococeus （CE） in Maqu and Luqu counties. Hydatid disease prevalence was 3.32% and 1% in the two counties. Different rates of hydatid disease prevalence were due to different age groups, different types of water, and different numbers of domestic dogs. Conclusion Human echinococcosis is widespread in Gannan Tibetan Autonomous Prefecture.
