Abstract
In October 2013, Porcine epidemic diarrhea (PED) was confirmed in Japan for the first time in seven years. Since then, the outbreak has spread nationwide, and more than new 100 cases per week were confirmed in April 2014 when the largest number of cases was confirmed. Then, the number of new cases started to decline and, so far, 822 cases in total have been confirmed in 39 prefectures as of 31 October. Under the circumstances, the Ministry of Agriculture, Forestry and Fisheries has been implementing actions to prevent further PEDV spread, for instance, by carrying out thoroughly the control measures based on the interim report on the epidemiological investigation and the comprehensive guidelines on PED control publicized this October.
