SUMMARY:

In Brazil, equine infectious anemia (EIA) has been a notifiable disease for the official veterinary service (SVO) since 1981. Due to the requirement to test negative for EIA for equine movement, most of the suspect cases are found with serological testing. The main measures to control and eradicate the disease are segregation and the slaughter of seropositive animals. Several studies have shown that the prevalence of the disease in Brazil is very variable and in many cases it is not possible to identify risk factors due to the low positivity rate. This study aimed to identify the characteristics of establishments with horses and estimate the seroprevalence of EIA in the Federal District -DF. The sample design was devised to target different types of holdings registered with the SVO-DF and identify possible risk factors. A total of 52 stud farms, 51 shared holdings for draft horses, 157 rural farms, 8 riding clubs, 3 veterinary hospitals and 2 military units were sampled, totaling 273 establishments. The sample included 2,482 equines, of which 10 were donkeys, 95 were mules and 2,377 were horses. An epidemiological questionnaire was used to characterize the holdings, covering environmental, organizational and health aspects. It was possible to conclude that rural farms and shared holdings for draft horses, due to their organizational and sanitary characteristics, have the potential to act as reservoirs and spreaders of EIA, respectively. Only these two typologies had animals that reacted to the disease (8/2,482), and the prevalence between them showed no significant difference. Animal prevalence was estimated at 0.65% (95% CI |0.37-1.05%|) and herd prevalence was 2.5% (95% CI |0.99-5.1% |). Animals that had not been tested for the disease over the last year had a higher prevalence of the disease than tested equids. The prevalence as also higher in mules compared to horses.
