## Pig cholera

Gifu Prefecture announced that it was infected with a domestic animal infectious disease "pig cholera" although on November 26, 2018, it was found in a town wading field in the carcass of a wild boar. According to the prefecture, it is the first time that infected wild boar was found in the town. Neighbors found and delivered to the town. Because it was out of the area covered by the prefecture's survey, after examining the prefecture, we also conducted genetic tests at national research institutes, and both were positive. Furthermore, on December 2, it was also revealed that male wild boars captured by Kageuri trap in Yaotsu town (near Nanyo Temple) were infected with swine fever.
