This work provides a systematic review and meta-analysis of the last 40 years (1981–2020) of scientific publications on SRLV individual and flock prevalence. Fifty-eight publications and 314 studies were included. Most articles used a single diagnostic test to estimate prevalence (77.6%), whereas articles using three or more tests were scarce (6.9%). Serological tests are more frequently used than direct methods and ELISA has progressively replaced AGID over the last decades. SRLV infection in sheep is widespread across the world, with Europe showing the highest individual prevalence (40.9%) and being the geographical area in which most studies have been performed. Africa, Asia, and North America show values between 16.7% to 21.8% at the individual level. South and Central America show the lowest individual SRLV prevalence (1.7%). There was a strong positive correlation between individual and flock prevalence (¿ = 0.728; p = 0.001). Despite the global importance of small ruminants, the coverage of knowledge on SRLV prevalence is patchy and inconsistent. There is a lack of a gold standard method and a defined sampling strategy among countries and continents. info:eu-repo/grantAgreement/ES/DGA/A17-20R info:eu-repo/grantAgreement/ES/MCIU/RTI2018-096172-B-C31 info:eu-repo/grantAgreement/ES/MCIU/RTI2018-096172-B-C33 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.231 2021 VETERINARY SCIENCES 16 / 145 = 0.11 2021 Q1 T1 AGRICULTURE, DAIRY & ANIMAL SCIENCE 13 / 63 = 0.206 2021 Q1 T1 0.61 2021 Veterinary (miscellaneous) 2021 Q1 Animal Science and Zoology 2021 Q1 2.7 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Arrieta, Marta Rodríguez-Largo, Ana Universidad de Zaragoza (orcid)0000-0002-2685-1730 Echeverría, Irache Resendiz, Raúl Pérez, Estela Ruiz, Héctor Universidad de Zaragoza (orcid)0000-0002-8474-2831 Pérez, Marta Andrés, Damián de Reina, Ramsés Blas, Ignacio de Universidad de Zaragoza (orcid)0000-0002-1204-4356 Luján, Lluis Universidad de Zaragoza (orcid)0000-0002-2053-9842 1009 773 Universidad de Zaragoza Dpto.
