Environmental stressors and zoonoses in the Arctic: Learning from the past to prepare for the future.

The risk of zoonotic disease transmission from animals to humans is elevated for people in close contact with domestic and wild animals. About three-quarters of all known human infectious diseases are zoonotic, and potential health impacts of these diseases are higher where infectious disease surveillance and access to health care and public health services are limited. This is especially the case for remote circumarctic regions, where drivers for endemic, emerging, and re-emerging zoonotic diseases include anthropogenic influences, such as pollution by long-range transport of industrial chemicals, climate change, loss of biodiversity and ecosystem alterations. In addition to these, indirect effects including natural changes in food web dynamics, appearance of invasive species, thawing permafrost also affect the risk of zoonotic disease spill-over. In other words, the Arctic represents a changing world where pollution, loss of biodiversity and habitat, and maritime activity are likely driving forward occurrence of infectious diseases. As a broad international consortium with a wide range of expertise, we here describe a selection of case studies highlighting the importance of a One Health approach to zoonoses in the circumarctic, encompassing human health, animal health, and environmental health aspects. The cases highlight critical gaps in monitoring and current knowledge, focusing on environmental stressors and lifestyle factors, and they are examples of current occurrences in the Arctic that inform on critically needed actions to prepare us for the future. Through these presentations, we recommend measures to enhance awareness and management of existing and emerging zoonoses with epidemic and pandemic potential while also focusing on the impacts of various environmental stressors and lifestyle factors on zoonoses in the Arctic.

Age-inclusive Arctic outdoor spaces: a policy review in four Nordic countries.

In the last decade, policy strategies were adopted in response to population ageing in the Nordic countries. Governmental actions have to be evaluated in terms of their efficacy. The objective of this article is to identify and review the policies related to age-inclusive outdoor spaces in the Arctic regions of Nordic countries. Our analysis focuses on central government white papers that address the older adults in Finland, Norway, Sweden, and Iceland. A review of such policy documents provides insights into the predominant understandings of older adults and healthy ageing. Moreover, such analysis may identify "blind spots" in the national policies, especially regarding the sparsely researched northernmost and rural Arctic territories. Our results demonstrate how the older populations in the Nordic Arctic and their access to outdoor spaces are addressed in the policy documents. We found that with few exceptions, the older people of the rural Arctic is strikingly absent in the Nordic national governmental papers. Moreover, access to outdoor spaces is mentioned in general terms, and specific challenges of the rural Arctic context, such as the harsh climate, long winters and geographical distances are not addressed. The noticed omissions might be the result of "urban-rural", "south-north", "indoor-outdoor", and "generalisation" biases.

Research on Selected Wildlife Infections in the Circumpolar Arctic-A Bibliometric Review.

One Health, a multidisciplinary approach to public health, which integrates human, animal, and environmental studies, is prudent for circumpolar Arctic health research. The objective of our bibliometric review was to identify and compare research in select infectious diseases in Arctic wildlife species with importance to human health indexed in English language databases (PubMed, Scopus) and the Russian database eLibrary.ru. Included articles (in English and Russian languages) needed to meet the following criteria: (1) data comes from the Arctic, (2) articles report original research or surveillance reports, (3) articles were published between 1990 and 2018, and (4) research relates to naturally occurring infections. Of the included articles (total n = 352), most were from Russia (n = 131, 37%), Norway (n = 58, 16%), Canada (n = 39, 11%), and Alaska (n = 39, 11%). Frequently reported infectious agents among selected mammals were Trichinella spp. (n = 39), Brucella spp. (n = 25), rabies virus (n = 11), Echinococcus spp. (n = 10), and Francisella tularensis (n = 9). There were 25 articles on anthrax in eLibrary.ru, while there were none in the other two databases. We identified future directions where opportunities for further research, collaboration, systematic reviews, or monitoring programs are possible and needed.

Caregiving of Older Persons during the COVID-19 Pandemic in the Russian Arctic Province: Challenges and Practice.

Older people and their families were particularly affected during the COVID-19 pandemic in 2020, but not much is known about the context of the Arctic regions of Russia. In this study, we identified the changes in family care before and during the pandemic using a questionnaire for the informal caregivers of older people. We investigated how and to what extent the pandemic has affected the relationships between caregiver and older person, and how the mental and physical health of older people and caregivers were affected by self-isolation in the Arkhangelsk region of Russia. The pandemic has changed the contribution of care from various actors: the share of care by charities, churches, and other aid agencies increased, while that of municipal services decreased. Sixteen percent of female and forty percent of male caregivers informed the study that COVID-19-related restrictions led to deterioration in the health of older people cared for at home. Family caregivers' own health worsened, especially mental health: 28% of caregivers reported aggravated stress during the COVID-19 pandemic and expressed various fears. Our data show that the main resources in overcoming the period of self-isolation have been telephone communication, personal contact, reading/music, friends, as well as the help of social services and maintaining a positive attitude.

Human infectious diseases and the changing climate in the Arctic.

Climatic factors, especially temperature, precipitation, and humidity play an important role in disease transmission. As the Arctic changes at an unprecedented rate due to climate change, understanding how climatic factors and climate change affect infectious disease rates is important for minimizing human and economic costs. The purpose of this systematic review was to compile recent studies in the field and compare the results to a previously published review. English language searches were conducted in PubMed, ScienceDirect, Scopus, and PLOS One. Russian language searches were conducted in the Scientific Electronic Library "eLibrary.ru". This systematic review yielded 22 articles (51%) published in English and 21 articles (49%) published in Russian since 2012. Articles about zoonotic and vector-borne diseases accounted for 67% (n = 29) of the review. Tick-borne diseases, tularemia, anthrax, and vibriosis were the most researched diseases likely to be impacted by climatic factors in the Arctic. Increased temperature and precipitation are predicted to have the greatest impact on infectious diseases in the Arctic.

Temporal trends of contaminants in Arctic human populations.

The first Arctic Monitoring and Assessment Programme (AMAP) report was published in 1998 and followed by three assessment reports of human health (AMAP 2003, 2009 and 2015). The focus area of the AMAP reports was to monitor levels of environmental contaminants in the Arctic and to assess the health effects connected with detected levels in Arctic countries. This review gives an overview of temporal trends of contaminants and their health effects in humans of the Arctic based on data published by AMAP, as well as Russian scientific literature. Several time series of 31 contaminants in humans of the Arctic from different cohorts are reported. The lengths of time series and periods covered differ from each other. International restrictions have decreased the levels of most persistent organic pollutants in humans and food webs. Percentage changes for contaminants in human biological matrices (blood samples from children, mothers and males and breast milk samples) for the period of sampling showed declining trends in most of the monitored Arctic locations, with the exception of oxychlordane, hexachlorobenzene (HCB), 2,2',4,4',5,5'-hexabromodiphenyl ether (PBDE153) and perfluorinated compounds (PFCs).
