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
Articles selected for full text review (n=14) Articles included in review (n=1) Initial search results (n=156) PubMed ScienceDirect Scopus Articles selected for full text review (n=6) Articles included in review (n=0) Initial search results (n=27) Articles selected for full text review (n=73) Articles included in review (n=20) Initial search results (n=674) PLOS One eLibrary.ru Articles selected for full text review (n=2) Articles included in review (n=1) Initial search results (n=58) Articles selected for full text review (number of articles not recorded) Articles included in review (n=21) Initial search results (n=2377)

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
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
Anthrax
- Permafrost thaw exposes buried carcasses of
infected animals
- Primary method of exposure is contact with
infected animals
- Low or absent vaccination

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
