Canids, especially domestic dogs, are definitive hosts of the parasite and are the most pragmatic targets for control programs. A governmental dog deworming campaign was established in 1979 to control hydatidosis in southern Chile, which succeeded in reducing the prevalence of canine echinococcosis in Tierra del Fuego <jats:italic>province<\/jats:italic> from 68.4% (in 1978) to 1.2% (in 2002). In 2004, however, the program was dismantled to reduce costs, and since then, no follow\u2010up echinococcosis monitoring has been conducted. We surveyed 356 domestic dogs and interviewed owners or workers at 45 ranches in Chilean Tierra del Fuego during the summer of 2015\u20132016. Faecal flotation was employed to detect Taeniidae eggs, and PCR was used to test faecal samples for <jats:italic>Echinococcus granulosus<\/jats:italic>. Taeniidae eggs and <jats:italic>Echinococcus<\/jats:italic> sp. DNA were detected in the faeces of 45.4% (147\/324) and 6.9% (23\/331) of dogs, respectively. Infrequent dog deworming and the presence of culpeo foxes (<jats:italic>Lycalopex culpaeus<\/jats:italic>) were significant predictors of the prevalence of <jats:italic>Echinococcus<\/jats:italic> sp. DNA and Taeniidae eggs. Furthermore, the presence of introduced chilla foxes (<jats:italic>Lycalopex griseus<\/jats:italic>), the municipality, and several operational characteristics of ranches (number of sheep, frequency of sheep slaughter, number of dogs, frequency of removal of dog faeces, feeding of dogs with sheep viscera) were also predictive of the prevalence of Taeniidae eggs. Our findings reveal an ongoing risk of echinococcosis with pathogen maintenance in ranch dogs in Chilean Tierra del Fuego, and in the absence of adequate control programmes, there is a tangible risk of re\u2010emergence of hydatid disease as a public health concern.<\/jats:p>","DOI":"10.1111\/zph.13017","type":"journal-article","created":{"date-parts":[[2022,12,14]],"date-time":"2022-12-14T07:16:34Z","timestamp":1671002194000},"page":"213-222","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Increased prevalence of canine echinococcosis a decade after the discontinuation of a governmental deworming program in Tierra del Fuego, Southern Chile"],"prefix":"10.1111","volume":"70","author":[{"given":"Eric James Lutz","family":"Eisenman","sequence":"first","affiliation":[{"name":"One Health Institute, School of Veterinary Medicine University of California  Davis California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3525-541X","authenticated-orcid":false,"given":"Marcela Maria","family":"Uhart","sequence":"additional","affiliation":[{"name":"One Health Institute, School of Veterinary Medicine University of California  Davis California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7476-5776","authenticated-orcid":false,"given":"Alejandro","family":"Kusch","sequence":"additional","affiliation":[{"name":"Wildlife Conservation Society \u2013 Chile  Punta Arenas Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alejandro Ruben","family":"Vila","sequence":"additional","affiliation":[{"name":"Wildlife Conservation Society \u2013 Chile  Punta Arenas Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ralph Eric Thijl","family":"Vanstreels","sequence":"additional","affiliation":[{"name":"One Health Institute, School of Veterinary Medicine University of California  Davis California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonna Ann Keener","family":"Mazet","sequence":"additional","affiliation":[{"name":"One Health Institute, School of Veterinary Medicine University of California  Davis California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8999-650X","authenticated-orcid":false,"given":"Crist\u00f3bal","family":"Brice\u00f1o","sequence":"additional","affiliation":[{"name":"Conserlab, Departamento de Medicina Preventiva Animal, Facultad de Ciencias Veterinarias y Pecuarias Universidad de Chile  Santiago Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,12,13]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0022149X99000487"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.4067\/S0717\u201077122005000100013"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijppaw.2021.09.002"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.4269\/ajtmh.2008.78.777"},{"key":"e_1_2_9_6_1","unstructured":"Centers for Disease Control and Prevention (CDC).
