Eastern and Western Equine Encephalitis Cases and Surveillance Information


Surveillance Information

Reports of equine cases of arboviral (i.e., arthropod-borne virus) diseases, including eastern and western equine encephalitis, are reported to ArboNet, an electronic-based surveillance and reporting system used to track and report arboviral activity. ArboNet captures laboratory-confirmed positive cases in humans, horses, other mammals, birds and mosquitoes across the United States. Equine case-finding varies by State, but primarily relies on passive reporting from private practitioners and diagnostic submissions. In some States, reporting is mandatory.
