This disease is a severe problem for small ruminant production, not only for animals’ well-being but also for flocks’ efficiency. The main aim of this research was to quantify the seroprevalence and associated risk factors for SRLV infection in the northern region of Portugal. Samples were collected from a total of 150 flocks, of which 129 (86.0%; 95% CI: 80.67%–91.33%) had at least one seropositive animal. Out of 2607 individual blood samples, 1074 (41.2%) were positive for SRLVs. Risk factors associated with SRLV infection were species (caprine), age (>2 years old), flock size (>100 animals), production system (intensive), food production system (milk), type of activity (professional), participation in livestock competitions (yes), replacement young ewe bought (yes), and natural feeding management (yes). This knowledge empowers the implementation of effective preventive measures. Overall, biosecurity measures should be promoted and implemented with the main aim of reducing viral transmission and reducing the prevalence of this disease. We recognise that government authorities should promote and audit voluntary control and eradication programs in small ruminant flocks in the region studied. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.3 2023 MICROBIOLOGY 70 / 161 = 0.435 2023 Q2 T2 0.843 2023 Immunology and Allergy 2023 Q2 Immunology and Microbiology (miscellaneous) 2023 Q2 Molecular Biology 2023 Q2 Microbiology (medical) 2023 Q2 Infectious Diseases 2023 Q2 6.4 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Coelho, Ana Cláudia Grau Vila, Ana Lacasta, Delia Universidad de Zaragoza (orcid)0000-0002-7822-6646 Quintas, Hélder 1009 617 Universidad de Zaragoza Dpto.
