“…According to previous reports, person-to-person transmission of SFTSV to HCWs can occur through contact with blood or respiratory secretions [7] and through aerosol transmission during resuscitation in HCWs [11]. Transmission is reported through direct contact, aerosol transmission [12], and through frequent personal contact [4, 5] in household members of primary patients. A previous study has suggested that person-to-person transmission might occur via direct contact with blood or bloody discharge [13].…”

“…SFTS is largely observed among farmers involved in agricultural activities as well as forest workers, and the majority of cases are reported in people of 50 years of age or older [2, 3]. Although SFTS is tick-borne disease, some studies have reported that SFTSV can be transmitted from person to person [4–6]. As this transmission is mostly driven by close contact to the index case, SFTS has been reported in healthcare workers (HCWs) [7], and asymptomatic infections have been noted in family members with close contact [4, 5].…”

We identified a healthcare-associated infection of severe fever with thrombocytopenia syndrome (SFTS) virus (SFTSV), transmitted through direct blood contact with an index case. Following further epidemiological and clinical investigations, we identified SFTSV seropositivity in 2 healthcare workers and 2 family members, who were positive for anti-SFTSV immunoglobin G. It is important to prevent SFTSV transmission by early diagnosis of SFTS and universal precautions.

“…The SFTSV has been detected in several species of ticks including Haemaphysalis longicornis . Person-to-person transmission of the SFTSV is possible through close contact between healthcare workers and family members [8910]. SFTSV and anti-SFTSV antibodies have been identified among ticks, domestic and wild animals, and humans in nature in endemic areas [1112].…”

BackgroundSevere fever with thrombocytopenia syndrome (SFTS) is a tick-borne zoonotic disease that is caused by the SFTS virus (SFTSV), and exhibits an overall mortality rate of approximately 20.0% in Korea. Most cases of this disease have been reported in Korea, East China, and Japan, and it mostly affects outdoor workers and farmers. This study aimed to investigate the seroprevalence of SFTSV among healthy farmers on Jeju Island, Korea.Materials and MethodsIn this prospective cross-sectional study, we analyzed 421 blood samples obtained from 254 farmers (mean age, 59.9 years; 68.9% male) to determine the seroprevalence of SFTSV in 16 rural areas of the Jeju Special Self-Governing Province over a period of 3 years (January 2015–December 2017). We used an enzyme-linked immunosorbent assay to detect immunoglobulin (Ig) G antibodies against SFTSV in the collected samples.ResultsThe seroprevalence of the SFTSV IgG among farmers on Jeju Island was observed to be 2.4%. One subject showed seropositivity over the entire 3-year study period. The areas with the highest SFTSV IgG seropositivity rates were Seonheul-ri in Jocheon-eup, followed by Namwon-eup. Fruit farmers were at a higher risk of exposure to SFTSV than other farmers.ConclusionThe seroprevalence of SFTSV in the healthy agricultural population of Jeju Island was not high. However, personal hygiene management should be implemented for the agricultural population in the endemic areas. Surveillance of mild or asymptomatic infections is required in the endemic regions.

“…SFTSV에 감염되면 고열이 나고 설사, 구토 등 소화기 증상을 호소하며 혈액검사 에서 혈소판 및 백혈구 수 감소가 동반되며 회복 되지 않는 경우 빠르게 다발성 장기기능 장애로 진행하여 사망에 이르게 된다 [6]. 일반적으로 농ㆍ 축산업, 임업에 종사하는 집단, 야외활동을 하는 사람들 등, 진드기와 접촉기회가 많은 사람에서 주로 발생하며, 의료기관에서 중증의 SFTS 환자 와 접촉한 의료진, 지역사회에서 SFTS환자와 함 께 거주한 가족에서도 감염이 가능하다 [7][8][9] [2]. 일본에서는 2013년 1월 초에 첫 사례가 보 고된 이후 산발적인 발생이 지속되고 있다 [10].…”

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging tick-borne infectious disease that is caused by the genus phlebovirus in the family Bunyaviridae. The syndrome is characterized by fever, gastrointestinal symptoms, neutropenia, and thrombocytopenia. The number of reported cases and deaths in endemic areas, such as China and Japan, has increased each year. Since the first SFTS patient was identified in 2013, the number of cases have also been increasing every year in South Korea and the disease is posing a great public health concern. The number of patients is increasing and there is a high mortality rate, but there is no established treatment that has proven to be effective. The purpose of this review was to elucidate the various treatment modalities, such as plasma exchange, antiviral agents, e.g. ribavirin, high-dose steroids, and interferon.
