Description
As the terrestrial realms of the Arctic thaw with climate change, relative southern infectious diseases carried by vector organisms such as ticks and mosquitoes may migrate with landscape transitions and expand into the far North. The OneHealth effects of such potentially expanding climate sensitive infections (CSI’s) constitute a serious global threat. To identify CSI’s, data concerning human infections were procured from national health reporting systems to cover the current thirty-year climate reference period from western Greenland to the pacific coast of Russia, from approximately 55 to 80 degrees north. The diseases chosen for their relevance to northern communities were borreliosis, brucellosis, cryptosporidiosis, leptospirosis, Puumala haemorrhagic fever, Q-fever, tick-borne encephalitis, and tularaemia. Together, these diseases represent a variety of spreading processes that apply to many human and animal diseases. Inferential results indicate that several of these infections are due to significant regional geographic translation and/or expansion trends, and that the associated northern societies hence are due to changing CSI exposure. In addition, for each of the selected infections, their respective thirty-year average incidences were used to define “diseases climates” for future reference.
