Bottom Line: SFTS is endemic to Nagasaki in western Japan; however, epidemiological information regarding SFTSV in Nagasaki is not known.SFTSV seropositive animals were found in three areas.Our findings provide epidemiological information on the distribution of SFTSV in Nagasaki.

ABSTRACT
Severe fever with thrombocytopenia syndrome (SFTS) is an emerging disease in East Asia. It is thought that the SFTS virus (SFTSV) circulates between ticks and animals in nature and that the virus is transmitted to humans by tick bites. SFTS is endemic to Nagasaki in western Japan; however, epidemiological information regarding SFTSV in Nagasaki is not known. In this study, we performed SFTSV IgG ELISAs and neutralization antibody assays for a seroepidemiological survey using samples from wild boars captured in six areas of Nagasaki. SFTSV seropositive animals were found in three areas. Our findings provide epidemiological information on the distribution of SFTSV in Nagasaki.

Mentions: A total of 190 serum samples were collected from wild boars that were captured in six areas of the Nagasaki prefecture (Fig. 1) from 2006 to 2012 for wild boar control conducted by Nagasaki prefecture. Samples were from juvenile (184 samples) and adult (6 samples) animals. The sera were inactivated at 56 °C for 30 min.Fig. 1
