16 Regional vector surveillance centers against
climate change

It is a project to provide surveillance information through monitoring real-time information on infectious disease vectors and vector-borne diseases due to climate change and environmental changes.

Regional vector surveillance centers against climate change

Operation of regional vector surveillance centers against climate change. It is a project to provide surveillance information through monitoring real-time information on infectious disease vectors and vector-borne diseases due to climate change and environmental changes.

Background

  • The recent rise in the incidence of vector-borne disease caused by wide distribution and high density of infectious disease vectors due to climate change.
  • A high possibility of introduction of infectious disease vectors and vector-borne diseases in Korea due to increasing international trade.
  • Continuous surveillance of vectors and pathogens at the surveillance centers is necessary to monitor the occurrence of vector-borne diseases and to provide prompt responses.

Overview

Participating Institutions: 11 Universities and 2 Institutes of Health and Environment Regional vector surveillance centers : 16 centers (Capital 1, Capital 2, Gyeonggi, Gangwon 1, Gangwon 2, Chungcheong 1, Chungcheong 2, Chungcheong 3, Jeonbuk, Jeonnam 1, Jeonnam 2, Gyeongbuk 1, Gyeongbuk 2, Gyeongnam 1, Gyeongnam 2, Jeju) Operating system of vector surveillance center

  • Vectors and Pathogens
mosquito
mite
tick
  • Main arthropod vectors of medical importance are mosquitoes, mites, and ticks.
  • The following pathogens (viruses and bacteria) transmitted by the vectors give rise to public health concerns: Japanese encephalitis virus (JEV), Dengue fever virus (DNV), West Nile virus (WNV), yellow fever virus (YFV), Zika virus, severe fever with thrombocytopenia syndrome virus (SFTS) virus, and Orientia tsutsugamushi.
  • Surveillance period
    • The national monitoring periods for investigating the density and prevalence of the major vectors are from March to November. However, depending on the vectors' biological activities, sampling period and frequency are different; mosquitoes are collected twice a month all year around, mites once a week from September to November, and ticks are overseen once a month from April and November.
    • A national survey of the distribution of the vectors has been also conducting at three-year intervals, in consecutive order of ticks to mites, to mosquitoes (tick->mite->mosquito).
