Objective To discuss the clinical manifestations and epidemiological characteristics of patients with intestinal taeniasis. Methods Clinical manifestations of 35 patients with intestinal taeniasis in a hospital in Beijing from January 2012 to July 2022 were summarized, and the epidemiological characteristics of the patients were analyzed. Results 35 cases of intestinal taeniasis all expelled proglottides, in which 18 cases(51.43%) were infected with Taenia saginata, and 17 cases(48.57%) with Diphyllobothrium latum. 11 cases(31.43%) had clinical manifestations including abdominal pain and abdominal distension;2 cases each had perianal itching or dizziness(5.71% for each);1 case each had nausea and vomiting, diarrhea, fever or weight loss(2.86% for each);16 cases(45.71%) were asymptomatic. 21 cases(60.00%) were local cases in Beijing, and the rest were from other provinces. 31 patients(88.57%) had a history of eating raw or half-raw food. Conclusion Most patients with intestinal taeniasis have no clinical symptoms or only slight gastrointestinal symptoms, and are prone to be misdiagnosed.
