Summary: To gain a better understanding of the epidemio- logical situation of arboviral infections in horses in Costa Rica, a national IgG seroprevalence study was performed in 2013. In Costa Rica, equine arboviral infections are caused by Alphaviruses such as Eastern equine encephalomyelitis virus (EEV), Western equine encephalomyelitis virus (WEV) and Venezuelan equine encephalomyelitis virus (VEV), as well as a Flavivirus: West Nile Virus (WNV). This study was carried out in response to a number of lethal disease outbreaks in horses, which were primarily caused by VEV, but also WNV and EEV. Arboviruses, which are transmitted to horses and humans through blood-sucking mosquitoes, may cause pyrexia, neurological disease and even death in both animals and humans.
