Outbreak of bovine ephemeral fever (BEF) have recorded seven times in Taiwan. Recurrence was recently found in Tainan county in August 2004. From August 23 to September 30, we carried out an epidemiological survey on 128 farms which contained 23,321 cattle. Thirty farms (23.4%) were suspected suffering from BEF based on the presence of fever and lameness. The morbidity was 0.7% (164/23,321) and the fatality was 14% (23/164). Blood samples of thirty-four cattle were collected from ten dairy farms for antibody titration and virus isolation. In addition, two cattle were necropsied for pathological and virus detections. The outbreak was diagnosed as BEF on the bases of clinical signs, pathological lesions, virus isolation, mouse inoculation, electromicroscopic examination, RT-PCR assay and nucleotide sequencing.
