Japanese encephalitis virus (JEV) causes a mosquitoborne viral zoonosis that is becoming increasingly important to public health in east and south Asia. Although JEV is primarily associated with reproductive failure in swine, JEV infection can cause fever and headache in humans and is associated with aseptic meningitis and encephalitis. The exact mode of transmission, including host range and possible source of viral amplification within livestock, is still not completely clear. This study consisted of a serological survey of JEV infection in goats. A total of 804 goat serum samples were collected from 144 farms in Korea between May 2005 and May 2006. The incidence of positive cases was 12.1% (97 out of 804 goats). The seroprevalence of JEV infection in the 144 farms screened was 31.3% (45/144), indicating that JEV infection is frequent in goat farms in Korea. In addition, three districts of Korea (mainly in the southern region) had a higher seroprevalence of JEV compared to other areas. The results suggest that goats could be monitored epidemiologically as a sentinel animal for JEV transmission in Korea.
日本脑炎病毒（JEV）引发一种由蚊子传播的病毒性人畜共患病，这对东亚和南亚的公共卫生正变得越来越重要。尽管JEV主要与猪的繁殖障碍有关，但JEV感染可导致人类发热和头痛，并与无菌性脑膜炎和脑炎相关。其确切的传播方式，包括宿主范围以及家畜体内病毒可能的扩增来源，仍不完全清楚。本研究包括对山羊JEV感染的血清学调查。2005年5月至2006年5月期间，从韩国144个农场共采集了804份山羊血清样本。阳性病例的发生率为12.1%（804只山羊中有97只）。在筛查的144个农场中，JEV感染的血清阳性率为31.3%（45/144），表明韩国的山羊养殖场中JEV感染很常见。此外，韩国的三个地区（主要在南部地区）JEV的血清阳性率高于其他地区。结果表明，在韩国，山羊可作为JEV传播的哨兵动物进行流行病学监测。
