Global Prevalence of Q Fever in Camels: A Systematic Review and Meta-Analysis of Studies From Africa and Asia.
Synthesis in Veterinary medicine and science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Q fever is a neglected zoonotic disease caused by Coxiella burnetii with a global distribution. It has a significant public health implication in resource-limited settings. Therefore, this systematic review and meta-analysis was designed to comprehensively analyse the global prevalence of Q fever in camels. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, online searches were conducted in Pubmed, ScienceDirect, Scopus, Web of Science and Google Scholar from 9 to 20 December 2025, to retrieve articles published between 1 January 2000 and 30 November 2025. After excluding articles that did not meet the inclusion criteria, this systematic review and meta-analysis identified 35 articles. After heterogeneity assessment, random effects model was used to estimate the pooled prevalence, and the overall pooled prevalence of Q fever in camels was 33.37% (95% CI: [23.14; 45.44]), combining serological evidence of previous or recent exposure with molecular evidence of C. burnetii detection. Diagnostic-method-specific analyses showed substantially different pooled estimates for ELISA (44.06%) and PCR (7.76%), reflecting distinct biological endpoints. The prevalence of Q fever was 37.17% in Africa and 26.87% in Asia. This meta-analysis result showed that the prevalence of Q fever is high in camels, but it is still neglected in several regions, posing significant impact to human and animal health. Expanded epidemiological investigations to underrepresented geographic regions and production systems will provide critical evidence to inform global surveillance strategies and support evidence-based policy for zoonotic disease prevention in camel populations and beyond.
