OBJECTIVE: To analyze the relevant information of echinococcosis cases from the National Web-based Infectious Diseases Report System in China in 2011. METHODS: Data of echinococcosis in 2011 were collected from the Report System of the Chinese Center for Disease Control and Prevention. SPSS 16.0 software was used to analyze the data. RESULTS: A total of 3 225 cases were reported in 2011, including 1 death and 3 013 effective cases. The three provinces (autonomous region) with high incidence were Xinjiang (occupying 41.5%, 1251/3013), Gansu (16.9%, 509/3 013) and Qinghai (12.0%, 363/3 013). Cases distributed in all age groups, with the highest incidence in the group of 31-40-year-old. Male to female ratio was 11.01. The incidence of farmers and herdsmen was highest. CONCLUSION: In 2011, the reported cases are mainly distributed in Xinjiang, Qinghai, Inner Mongolia, Gansu, Ningxia, Sichuan and Tibet. Echinococcosis is mainly prevalent in western China.
