• Surveillance of arbovirus-associated encephalitis was conducted in South Korean horses.
• Surveillance provided information on arboviral equine disease situation in South Korea.
• Continued surveillance will be required to detect new introductions.
Surveillance was conducted in South Korea to look for evidence of infection with Eastern equine encephalitis virus (EEEV), Western equine encephalitis virus (WEEV), Venezuelan equine encephalitis virus (VEEV), West Nile virus (WNV), St. Louis encephalitis virus (SLEV), and Japanese encephalitis virus (JEV) in horses from 2012 to 2013. The surveillance consisted of passive surveillance of testing horses with neurologic symptoms such as paralysis, incoordination, ataxia and circling, and active surveillance of testing for serologic evidence of infection in healthy horses. Passive surveillance was conducted for EEEV, WEEV, VEEV, WNV, SLEV, and JEV, and whole blood and/or brain samples received from 49 horses with neurologic signs were tested by polymerase chain reaction (PCR). Active surveillance was conducted for WNV and JEV, and 2,695 serum samples collected from horses across the country were tested for antibodies by IgM enzyme-linked immunosorbent assay (ELISA) and virus neutralization test (VNT), respectively. All samples tested by PCR were negative for EEEV, WEEV, VEEV, WNV, and SLEV, except for one whole blood sample (1/45) that was positive for JEV. All samples tested for WNV antibodies were shown to be negative. For JEV, because South Korea is endemic and horses in South Korea are vaccinated against JEV, various titers of antibodies for JEV were detected by VNT in 57.8% (737/1,274) and 58.9% (837/1,421) of the sera in 2012 and 2013, respectively. The surveillance provides evidence that supports the view that South Korea is free from EEEV, WEEV, VEEV, WNV, and SLEV. In addition, the surveillance scheme was shown to be able to identify JEV infections in the equine population and provide serologic data for JEV that could be used to improve the current vaccination program for JEV in horses.
