Equine infectious anemia (EIA) is an infectious disease affecting equine in most countries and represents a notifiable disease with compulsory euthanasia of positive animals. The present study aimed to determine the prevalence of EIAV infected equines in herds of the state of Goiás (Central Brazil) and to evaluate the risk factors associated with the occurrence of the disease. Blood samples were collected from 1170 equids from 332 randomly selected farms divided into three different strata according to their herd characteristics. Also, an epidemiological questionnaire was applied during the visit to the farm. Of the 332 farms evaluated, 12 (3.1%; 95% CI: 1.24 - 6.00) had at least one positive equine for EIA, and of the 1170 evaluated equines, 14 (2%; 95% CI: 0.31-3.00) were positive in agar gel immunodiffusion. Multivariate analysis revealed that the use of a vaccination pistol (p < 0.001) and the presence of water bodies inside the farm (p < 0.01) were risk factors associated with the occurrence of EIA. Thus, the present study demonstrated a low but widespread prevalence of EIAV infected animals in the herds of Goiás state and that iatrogenic and environmental risk factors were associated with the occurrence of the disease.
