Abstract
The Equine infectious anemia (EIA) is an infectious disease caused by the Equine infectious anemia virus, a lentivirus belonging to the Retroviridae family. EIA is an OIE listed disease. Infected horses will become carriers for life; therefore any horse with a positive result of serological test will be identified as infected. It’s typical clinical signs include high fever, anemia, and weight loss. Abortion may occur if pregnant mares are infected, and the virus can infect the fetus via the placenta. Most horses are infected with EIA with no obvious clinical signs as latent carriers, or in chronic stage with mild clinical signs. Both of latent carriers and chronically infected horses can show repeated severe clinical signs, even ending up with death. EIA serological test is necessary in the import and export of horses. There has been no investigation of EIA in Taiwan in the past ten years ever since 2001. In this study we took all 217 blood samples from the northern region (Taipei and Taoyuan, Hsinchu), the central region (Miaoli, and Taichung), the southern region (Kaohsiung and Pingtung), and the eastern region (Hualien and Taitung). Samples were tested by enzyme-linked immunosorbent assay (ELISA), and there is no positive result. It’s been 20 years we have no positive result in Taiwan since 1992. It can be seen as a huge success of our EIA elimination strategies, but still need to continuously investigate in the future.
