Objective To investigate and analysis the data of patients with hepatic echinococcosis in Ganzi County in 2018, and to understand the epidemiological characteristics of hepatic echinococcosis in Ganzi County, Sichuan Province.Methods A total of 811 patients were enrolled. The basic information of sex, age, weight, occupation, nation, educational level, family address and so on were recorded. The location, number, classification, transverse diameter and longitudinal diameter of hepatic echinococcosis masses were recorded by abdominal color Doppler ultrasonography.Results In 2018, 811 new cases of hepatic echinococcosis were reported in Ganzi County, with a prevalence rate of 4.6% (811/17 650), and 17.81% (572/3 212) in the Datongma area. Patients ranged in age from 6 to 92, the average age was (44.8±16.6) years old. The majority of patients were Tibetans (98.5%), herdsmen (71.8%) and illiterates (83.5%). The most common lesions were in right liver (84.2%) and single (91.4%).Conclusions There is serious transmission of hepatic echinococcosis in Ganzi County, especially in pure pastoral areas, and HAE is more prevalent than HCE. Most of the infected people are Tibetan herdsmen with illiterate educational background and more females than males. The peak incidence of hepatic echinococcosis is 30-55 years old. Close monitoring should be carried out for these people.
