| Outline of Final Research Achievements |
Porcine epidemic diarrhea virus (PEDV), causes acute diarrhea and dehydration in piglets, among which mortality rate can reach up to 100%. Syndromic surveillance has also been carried out as pig producers are obligated to inform farm veterinarians whenever the pigs demonstrate signs of diarrhea. Subsequently, PEDV infections are confirmed by veterinary authorities at Prefectural Livestock Hygiene Centers. Based on examination results, farms declared as PED-positive are classified under “case farms”. “Non-case farms” in Japan are defined as farms with no pigs showing PED clinical signs. Thus, the aim of this study was to identify infected or free farm, and compare risk factors associated with PED infection in Japan. As a result, the present study revealed risk factors related to the spread of PEDV in Japan.
