Abstract: Objective To understand the infection status of Sparganum mansoni in human and animal hosts in Xiangxi Autonomous Prefecture. Methods To collect and analyze the clinical cases and treatment records of patients with Sparganum mansoni  IgG antibody detection in parasite ward of Xiangxi Autonomous Prefecture CDC from 2010 to 2018,and epidemiological survey was conducted on the intermediate host and the host. Results Between 2010 and 2018,a total of 677 people (348 males and 329 females) underwent test of Sparganum mansoni infection. The results showed that 36 males and 20 female were positive for the antibody against Sparganum mansoni ,and the gender ratio was different( χ2 = 4. 06,P<0. 05). The oldest patient was 84 years old and the youngest one was 6 years old,and patients aged over 40 years accounted for 73. 21%. The difference was insignificant in different age group,ethnic group and occupations(P>0. 05). The most common infection was associated with intake of raw frogs and tadpoles,which accounted for 87. 50%. Forty-two pieces of Sparganum mansoni were detected in the frog muscles of 303 frogs dissected,with an infection rate of 13. 86%. Field microscopic examination of cat and canine feces revealed that the infection rate of Spirometra mansoni was 21. 74% and 5. 49%,respectively. Fifty-six patients were treated with surgery and praziquantel,albendazole and other drugs. Except for some brain types,other clinical types were cured. No obvious side effects occurred. Conclusion Spargnosis has become a common food-borne parasitic disease in Xiangxi Autonomous Prefecture. Infection with Spirometra Spagranum mansoni is prevalent in humans,frogs,
