The objectives of this review are to provide apparent small ruminant brucellosis prevalence\/positivity estimates across Africa by country, region, continent, and diagnostic modality. A systematic search was conducted on PubMed, ScienceDirect, and Google Scholar for articles published from 2000 to 2025. Data from 151 eligible studies representing 28 countries were extracted and meta-analyzed. Due to extreme heterogeneity (I2 &gt; 97%), a single continental pooled estimate is not epidemiologically meaningful. For descriptive reference, Africa\u2019s apparent pooled seroprevalence was 4.9% (95% CI: 3.0\u20137.5%; prediction interval: 0.1\u201332.1%), and pooled PCR positivity was 12.7% (95% CI: 6.0\u201321.9%; prediction interval: 0.8\u201338.9%). Descriptive regional seroprevalence ranged from 3.3% (95% CI: 1.2\u20137.4%) (West Africa) to 6.2% (95% CI: 3.8\u20139.4%) (East Africa). Country-level crude seroprevalence ranged from 0.18% (Morocco) to 19.53% (Libya), with diagnostic method prevalence ranging from 3.37% (2-Mercaptoethanol (2-ME)) to 21.54% (Whole Genome Sequencing (WGS)). Both B. abortus and B. melitensis are reported with significant variations. Data absence from several African countries highlights a critical knowledge gap. We propose multi-level prevention and control strategies.<\/jats:p>","DOI":"10.3390\/vetsci13070638","type":"journal-article","created":{"date-parts":[[2026,7,1]],"date-time":"2026-07-01T00:50:37Z","timestamp":1782867037000},"page":"638","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Prevalence of Brucellosis in Small Ruminants in Africa from 2000 to 2025: A Systematic Review and Meta-Analysis"],"prefix":"10.3390","volume":"13","author":[{"given":"Weldeab Solomon","family":"Ghebrezgabher","sequence":"first","affiliation":[{"name":"State Key Laboratory for Animal Disease Control and Prevention, College of Veterinary Medicine, Lanzhou University, Lanzhou Veterinary Research Institute, Chinese Academy of Agricultural Sciences, Lanzhou 730046, China"},{"name":"National Higher Education and Research Institute, Hamelmalo Agricultural College, Keren P.O.
