Increased Risk of Viral Spillover

Audrée Lemieux, Graham A. Colby, Alexandre J. Poulain, Stéphane Aris-Brosou: Viral spillover risk increases with climate change in High Arctic lake sediments, in: Proceedings of the Royal Society B. Biological Science Vol.  289, Issue 1985 (October 26, 2022) 20221073, online in: https://doi.org/10.1098/rspb.2022.1073. Abstract The host spectrum of viruses is quite diverse, as they can sustainedly infect a few species to several phyla. When confronted with a new host, a virus may even infect it and transmit sustainably in this new host, a process called ‘viral spillover’. However, the risk of such events is difficult to quantify. As climate change is […]

Interactions with the Climate

James D. Ford et al.: Interactions between climate and COVID-19, in: The Lancet Planetary Health Vol. 6,Issue 10 (October 2022) p. e825-e833, online in: https://www.doi.org/10.1016/S2542-5196(22)00174-7. Abstract In their Personal View, the authors explain the ways that climatic risks affect the transmission, perception, response, and lived experience of COVID-19. First, temperature, wind, and humidity influence the transmission of COVID-19 in ways not fully understood, although non-climatic factors appear more important than climatic factors in explaining disease transmission. Second, climatic extremes coinciding with COVID-19 have affected disease exposure, increased susceptibility of people to COVID-19, compromised emergency responses, and reduced health system resilience […]
