This cross\u2010sectional study investigated the seroprevalence of SARS\u2010CoV\u20102 neutralizing antibodies in livestock in Sarawak, Malaysian Borneo. Archived plasma samples collected between June and September 2024 from 180 livestock animals, including pigs, cattle, buffalo, sheep, and goats, were obtained from the Sarawak Veterinary Diagnostic Service Laboratory and tested using the GenScript cPASS surrogate virus neutralization test (sVNT), a species\u2010independent assay detecting antibodies that block the SARS\u2010CoV\u20102 spike receptor\u2010binding domain (RBD)\u2013ACE2 interaction. Overall, 19.4% (35\/180) of samples were seropositive using the manufacturer\u2010recommended cut\u2010off. Seroprevalence varied significantly by species, with the highest prevalence observed in goats (48.6%), followed by sheep (28.6%), cattle (11.4%), buffalo (8.3%), and pigs (2.6%), and also differed by sampling location but not by age group or sex. Most positive samples exhibited low\u2010level inhibition values near the assay cut\u2010off, suggesting weak or transient neutralizing antibody responses. Multivariable logistic regression identified species as the primary factor independently associated with seropositivity. Collectively, these findings are consistent with sporadic spillback exposure of SARS\u2010CoV\u20102 from humans into livestock in Sarawak, without evidence of widespread or sustained transmission among livestock populations. Periodic, risk\u2010based surveillance of livestock remains warranted to monitor potential changes in host susceptibility as SARS\u2010CoV\u20102 continues to evolve.<\/jats:p>","DOI":"10.1155\/tbed\/9927316","type":"journal-article","created":{"date-parts":[[2026,7,21]],"date-time":"2026-07-21T07:08:23Z","timestamp":1784617703000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Seroprevalence of SARS\u2010CoV\u20102 in Livestock in Sarawak, East Malaysia"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6312-4551","authenticated-orcid":false,"given":"Cheng Siang","family":"Tan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2125-2237","authenticated-orcid":false,"given":"Vaenessa","family":"Noni","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0442-0729","authenticated-orcid":false,"given":"Ahmad Syatir","family":"Tahar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carolynna Buyau","family":"James","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-8280-4068","authenticated-orcid":false,"given":"George","family":"Bobby","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jackie","family":"Peter","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,21]]},"reference":[{"key":"e_1_2_13_1_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41591-020-0796-5"},{"key":"e_1_2_13_2_2","doi-asserted-by":"publisher","DOI":"10.3389\/FVETS.2022.986619"},{"key":"e_1_2_13_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/vms3.1029"},{"key":"e_1_2_13_4_2","doi-asserted-by":"publisher","DOI":"10.3390\/microorganisms10020263"},{"key":"e_1_2_13_5_2","doi-asserted-by":"publisher","DOI":"10.3201\/EID2707.203314"},{"key":"e_1_2_13_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/J.VETMIC.2020.108777"},{"key":"e_1_2_13_7_2","doi-asserted-by":"crossref","DOI":"10.3390\/v14061178","article-title":"SARS-CoV-2 Infection in Companion Animals: Prospective Serological Survey and Risk Factor Analysis in France","volume":"14","author":"Bessi\u00e8re P.","year":"2022","journal-title":"Viruses"},{"key":"e_1_2_13_8_2","doi-asserted-by":"crossref","DOI":"10.1186\/s12985-023-02133-9","article-title":"Serosurveillance of SARS-CoV-2 in Companion Animals in Sarawak, Malaysia","volume":"20","author":"Tan C.
