Systematic Review

  • To compile recent studies in this field and

compare them to a previous review (Hedlund

  • et. al 2014)
  • English searches conducted in PubMed,

ScienceDirect, Scopus, and PLOS One

  • Russian searches conducted in the Scientific

Electronic Library “eLibrary.ru”

  • Searches conducted in March 2018

Airborne diseases

  • Influenza A and human rhinovirus were

investigated in relation to temperature and humidity

  • Abundance of co-factors
  • Low publication numbers
  • Difficult to establish an association

SLIDE 11

Food- and waterborne diseases

  • Lack of sanitation/ water infrastructure
  • Increased temperature and precipitation
  • Disruption of waste and sanitation

infrastructure

  • Increased use of public bathing areas
  • Vibriosis

– Associated with increases in sea surface temperature

Vector-borne diseases and zoonoses

Tick-borne diseases

  • Tick borne encephalitis

(TBE)

  • Tick borne borreliosis (TBB)
  • Warmer temperatures

affect habitat and life cycle Tularemia

  • Climatic and ecological

factors play important role in determining vector range and population

slide-13
SLIDE 13

Anthrax

  • Permafrost thaw exposes buried carcasses of

infected animals

  • Primary method of exposure is contact with

infected animals

  • Low or absent vaccination

  • Main focus of the 72 articles included in this review (n=43) and a previous review (n=29)

(Hedlund et al. 2014) divided by country

  • All articles published between 1970-2017
  • “Other” includes articles covering more than 1 country

Conclusion

  • Increasing amount of research in the field published

after 2010

  • Tick-borne diseases, tularemia, anthrax, and vibriosis

were the most researched infections likely to be impacted by climatic factors in the Arctic

  • Increased temperature and precipitation are predicted

to be the most influential climatic factors

  • Surveillance, continued research, education, and

vaccination can reduce the impact of climate associated changes in infections in the Arctic
