Abstract

Severe fever with thrombocytopenia syndrome (SFTS) is firstly reported in China in 2011. Thereafter it is reported an infectious disease in Japan and Korea. It is caused by bunyavirus, called SFTS virus (SFTSV). The main vector of SFTS is Haemaphysalis longicornis tick. We investigated the distribution and detection of SFTSV in ticks collected from the environment using the dragging method and dry ice fogging method from May to November 2014 in Jeollanam-do, Korea. Sampling was taken from the province Suncheon, Gokseong, Boseong, Goheung where patients have occurred in 2013 and Gurye as control. Among the total 3,048 ticks collected, 3,030 ticks were H. longicornis (99.4%) and 18 were Amblyomma testudinarium. H. longicornis was collected 1,330 ticks in Gokseong, 1,188 ticks in Boseong, 240 ticks in Suncheon, 150 ticks in Goheung and 140 ticks in Gurye. Developmental stages by month of H. longicornis were revealed that nymph (92%) was collected from May to June, adult (30%) and nymph (70%) in July, and 93% of larvae from September to October. These results showed the different dominant stage of ticks according to seasons. However, no SFTSV-specific gene was detected in 3,030 ticks of H. longicornis.
