  Severe fever with thrombocytopenia syndrome (SFTS) is a tick-borne disease caused by the SFTS virus (SFTSV). Since the first SFTS patient in Korea was reported in 2013, approximately 200 cases of SFTS have been reported annually for the past three years. In this study, the genotypes of 352 SFTSVs detected from SFTS suspected patient samples over the past three years (2017-2019) were analyzed to compare the genotypic epidemic patterns and distribution status of genotypes by region. This study further analyzed the annual and regional incidence of SFTS. As a result of analysis, six different genotypes of SFTSV were identified.
  Of the 352 SFTSV, the majority observed in genotype B accounted for 77.6% of the total genotypes identified, followed by genotype D (10.5%) and genotype A (6.3%). The detection rates of genotypes C, E and F were low; less than 10 cases over three years. For three consecutive years, genotype A occurred repeatedly in patients residing in Gyeonggi Province and Gangwon Province, and genotype D and E were persistently detected in patients residing in Chungnam Province. As a result of comparing the incidence rate per 100,000 people by region, Jeju Province and Gangwon Province showed higher rates of occurrence than other regions. In this study, there was a limit to the specifying the regional distribution pattern of the SFTSV genotype based only on the residential area information of each patient. However, theses results can be used as strategic data for the selection of genotype candidates for SFTS vaccine design and for the identification of diseases occurrence patterns associated with genotype changes by continuously monitoring in the genotype distribution of domestic SFTSV to control SFTS infectious diseases.

  Abstract

  Ebola virus disease outbreak have been reported sporadically since the first case reported at DR Congo in 1976. Zaire Ebola virus is one of the 6 sub species of Ebola virus which has continued to be epidemic in the last three years at DR Congo. The country is demonstrating control of deadly endemic diseases through the use of the Zaire Ebola virus vaccine and systematic response strategies. Response to the Ebola epidemic basically include control of the moving population, test, tracing of contacts, isolation and treatment, safe funeral, and training of health care worker. Characteristic strategies for Ebola endemic include ring vaccination, mother and child care, and survivor management. There are currently no reports of Ebola virus cases in Korea but the presence of natural host in Africa makes it unpredictable when the Ebola epidemic occurs. Also, the possibility of secondary infection through survivors cannot be ruled out, so symptom monitoring, voluntary report and management for those visited emerging areas are important.
