Recent settlement expansion in the region has raised concerns, as smaller, remote settlements often lacked waste disposal and sewage systems, potentially facilitating echinococcosis transmission. The aim of this study is to investigate how settlement characteristics influence echinococcosis transmission.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Findings<\/jats:title>\n                    <jats:p>\n                      The study was conducted from 2022\u20132024 in nomadic communities of Shiqu County in China.

Smaller, remote settlements had higher prevalence rates for both CE and AE. The density of owned dogs was a significant risk factor for CE prevalence but not for AE prevalence. Targeted interventions are needed in these high-risk settlements. Future research should investigate how settlement characteristics interact with hygiene practices, the infection status of intermediate and definitive hosts, and their population dynamics to better understand combined effects on echinococcosis prevalence.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1186\/s40249-025-01316-6","type":"journal-article","created":{"date-parts":[[2025,6,11]],"date-time":"2025-06-11T23:42:07Z","timestamp":1749685327000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Settlement characteristics and transmission of echinococcosis: a cross-sectional study in nomadic communities on the Qinghai-Tibet Plateau, China"],"prefix":"10.1186","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8639-5768","authenticated-orcid":false,"given":"Qian","family":"Wang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yifei","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhaohui","family":"Luo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sha","family":"Liao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenjie","family":"Yu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guangjia","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liu","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"He","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhongshuang","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diming","family":"Cai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guo","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongzhong","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruirui","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qi","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Renxin","family":"Yao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Quzhen","family":"Gongsang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2025,6,12]]},"reference":[{"key":"1316_CR1","unstructured":"Yu WJ, Wang Q, Liao S, Zhang GJ, He W, Yang L, et al.
