SFTS (Severe Fever and Thrombocytopenia Syndrome) is one of tick-borne diseases that RNA virus causes high fever vomiting, diarrhea, coma, and multiple organ failure. Since SFTSV was initially reported in 2011 in China, the Korea Centers for Disease Control (CDC) designated the SFTSV as the legal communicable disease county 4 in 2013. Infection occurs mainly during the period of June to October, and the numbers of infected people has increased every year. Older person have shown higher infection for SFTS, and SFTSV seroprevalence was 3-fold higher for rural farmers. Haemaphysalis longicornis reported as vector of SFTS is three-host tick, which has developmental stages of larvae, nymphs, and adults. The species who is distributed throughout Korea, has the habit climbing to the plant and waiting for host. Except for the time attached to the host animals, they usually live on the ground or plants. Their eggs hatch on ground under herbaceous plants in woody tree forests. All wildlife which include mammals, amphibians and avian, as well as livestock such as cattle, can become tick hosts. Host presence is driving force to affect tick lifecycle like survival, development, reproduction, dispersal. Thus, it is reported that number of infected tick or number of human infections are positively correlated with the density of roe deer in Europe. Wildlife, especially invasive mammal to human area, can be an important vector of H.longicornis who causes SFTSV. The purpose of this research is to identify the role of wildlife in the spread of tick-bone disease (SFTS) to human.
