Abstract
Classical swine fever (CSF) virus belongs to the members of the genus Pestivirus in the Flaviviridae family. This virus is a causative agent of economically important diseases for livestock and wild animals that occur worldwide, such as foot-and-mouse disease and African swine fever. In September 2018, CSF outbreaks were reported for the first time in 26 years in Japan, and so far 56 cases were reported. The cause of the virus spread is due to the virus transmissions in wild boars. It is necessary to continue thorough biosecurity in pig farms since it takes more time to eliminate CSF virus from wild boars. This article introduces the latest information on the viruses of the genus Pestivirus including CSF virus and the control measures against CSF in Japan.
