However, to our knowledge, the effect of bias towards feeding on the same host species from which a first meal was taken, termed fidelity, has not been quantified. Using a mathematical model we showed that vector fidelity to the host species they take a first blood meal from leads to non-homogeneous mixing between hosts and vectors. Taking Japanese encephalitis virus (JEV) as a case study, we investigated how vector preference for amplifying vs dead-end hosts and fidelity can influence JEV transmission. We show that in regions where pigs (amplifying hosts) are scarce compared to cattle (dead-end hosts preferred by common JEV vectors), JEV could still be maintained through vector fidelity. Our findings demonstrate the importance of considering fidelity as a potential driver of transmission, particularly in scenarios such as Bangladesh and India where the composition of the host community might initially suggest that transmission is not possible.<\/jats:p>","DOI":"10.1371\/journal.pntd.0012196","type":"journal-article","created":{"date-parts":[[2025,5,8]],"date-time":"2025-05-08T13:41:34Z","timestamp":1746711694000},"page":"e0012196","update-policy":"https:\/\/doi.org\/10.1371\/journal.pntd.corrections_policy","source":"Crossref","is-referenced-by-count":1,"title":["The potential impacts of vector host species fidelity on zoonotic arbovirus transmission"],"prefix":"10.1371","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9735-8548","authenticated-orcid":true,"given":"Tijani A.","family":"Sulaimon","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9973-8205","authenticated-orcid":true,"given":"Anthony J.","family":"Wood","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0250-0423","authenticated-orcid":true,"given":"Michael B.","family":"Bonsall","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3763-6136","authenticated-orcid":true,"given":"Michael","family":"Boots","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6616-1526","authenticated-orcid":true,"given":"Jennifer S.","family":"Lord","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2025,5,8]]},"reference":[{"issue":"3","key":"pntd.0012196.ref001","first-page":"143","article-title":"Blood-feeding arthropods: live syringes or invertebrate pharmacologists?","volume":"4","author":"J Ribeiro","year":"1995","journal-title":"Infect Agents Dis"},{"issue":"6","key":"pntd.0012196.ref002","doi-asserted-by":"crossref","first-page":"249","DOI":"10.1016\/j.pt.2004.03.007","article-title":"No accounting for taste: host preference in malaria vectors","volume":"20","author":"NJ Besansky","year":"2004","journal-title":"Trends Parasitol"},{"issue":"1","key":"pntd.0012196.ref003","doi-asserted-by":"crossref","first-page":"433","DOI":"10.1146\/annurev-ento-120811-153618","article-title":"Host preferences of blood-feeding mosquitoes","volume":"58","author":"W Takken","year":"2013","journal-title":"Annu Rev Entomol"},{"key":"pntd.0012196.ref004","doi-asserted-by":"crossref","DOI":"10.1079\/9780851993133.0000","volume-title":"The biology of mosquitoes.
