The PHI included three components: a vaccination clinic and accompanying clinic questionnaire; a serological investigation; and a cross-sectional study for consenting Australian-born participants who completed an extended questionnaire after receiving their serological results. The goals were to vaccinate a presumably na\u00efve population to reduce associated risk and to understand the seroprevalence among Australian-born piggery workers. \nA total of 322 farm workers and\/or residents attended clinics organised by NSW Health; 311 received a JEV vaccine (96.6%); and 302 (94%) completed a clinic questionnaire. Of 178 people from whom serology was collected (55.3%), a total of 165 returned Defined Epitope Blocking enzyme-linked immunosorbent assay (DEB ELISA) results; 153\/165 of those returning DEB ELISA results were Australian born. The study\u2019s cross-sectional component involved 129 participants, ten of whom were seropositive.\nThe overall seropositivity for 153 Australian-born participants across the identified piggeries was 6.5% (95% confidence interval [95% CI]: 3.4\u201312.0%), suggesting that JEV was circulating in piggeries, and plausibly more broadly, within the Murray region prior to serology collection. Male sex and working on, or visiting, a farm other than their regular workplace were both associated with JEV seropositivity (odds ratio [OR]: 5.4; 95% CI: 0.94\u2013137.1 and OR: 37; 95% CI: 0.92\u201322.08 respectively).<\/jats:p>","DOI":"10.33321\/cdi.2025.49.004","type":"journal-article","created":{"date-parts":[[2025,1,21]],"date-time":"2025-01-21T20:50:55Z","timestamp":1737492655000},"source":"Crossref","is-referenced-by-count":2,"title":["The detection of Japanese encephalitis virus (JEV) in the Murray region, New South Wales: a public health investigation"],"prefix":"10.33321","volume":"49","author":[{"given":"Gamuchirai","family":"Shava","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katherine","family":"Todd","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tracey","family":"Oakman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Linda","family":"Hueston","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keira","family":"Glasgow","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"April","family":"Roberts-Witteveen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"18788","published-online":{"date-parts":[[2025,1,22]]},"container-title":["Communicable Diseases Intelligence"],"original-title":[],"deposited":{"date-parts":[[2025,6,10]],"date-time":"2025-06-10T18:45:27Z","timestamp":1749581127000},"score":1,"resource":{"primary":{"URL":"https:\/\/ojs.cdi.cdc.gov.au\/index.php\/cdi\/article\/view\/2757"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,1,22]]},"references-count":0,"URL":"https:\/\/doi.org\/10.33321\/cdi.2025.49.004","relation":{},"ISSN":["2209-6051"],"issn-type":[{"value":"2209-6051","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,1,22]]}}}
