VALLEJO ROMERO, Richard Sidney et al. Prevalence of equine infectious anemia in Central America, the Caribbean and South America. Systematic Review and Meta-analysis. Rev Salud Anim. [online]. 2021, vol.43, n.2  Epub 27-Ago-2021. ISSN 2224-4700.

The aim of this study was to determine, through a systematic review and meta-analysis, the combined prevalence of equine infectious anemia (EIA) in domestic equids in South America, Central America and the Caribbean regions, in the period 2010-2021. Information was selected from articles published in the electronic databases PubMed/PubMed Central, Science Direct, Scielo, Ebsco and Google Scholar. Original articles and postgraduate theses, with full text available, were considered in the study, including domestic equids, using serological techniques recommended by the OIE and providing the sample size and number of positive samples. A meta-analysis to estimate the combined prevalence of the disease and a subgroup analysis were carried out to determine the effect of the geographic regions (South America, Central America and the Caribbean), the animal species (horses, donkeys and mules) and the period of publication of the articles (2010-2016 and 2017-2021). The effect of the groups on the combined prevalence was further assessed by meta-regression analysis. Forty-nine articles were included in the study, from which a combined prevalence of 11.8 % was determined (95 % CI: 10.3-13.5). The multivariate meta-regression analysis showed that there was an association of the combined prevalence of the disease with the study period and the animal species studied. It is concluded that there are few studies regarding the behavior of this disease in the regions studied, besides there was an association of the combined prevalence of the disease with the study period and the species studied.
