Abstract: Objective To analyze the status and trends of echinococcosis prevalence in the past 20 years for reference in domestic research of this infection. Methods Publications on the studies of echinococcosis were retrieved from 2001 to 2020 through CNKI database,and visually analyzed pertinent to the quantity of published studies,authors,research institutions and journals using CiteSpace and Excel 2019. Then the map on scientific knowledge in the field of hydatidosis research was developed. Results Totally,5 968 articles were retrieved. The publications were the most in 2018,with 484 articles appeared. Most studies(596) were contributed by The First Affiliated Hospital of Xinjiang Medical University,and by Wen Hao,whose contribution was 296 articles. Most articles were published in the Journal of Pathogen Biology (335) and Chinese Journal of Parasitology and Parasitic Diseases ( 291) . Research hotspots were primarily composed of " hydatid disease" ," hepatic alveolar echinococcosis" and " prevention and treatment" . Conclusion Research interest in echinococcosis has increased continuously from 2001 to 2020,and the research team consists of surgeons from affiliated hospitals of universities. The research institutions are mostly involved in areas with higher prevalence of echinococcosis,and the research hotspots are associated with diagnosis,treatment and prevention of this infection. Quantitative and visual analysis of current publications can lead to better understanding of the research interest and trends in echinococcosis as well as reference in the field of study of this entity.
