‘For well over a year we’ve been living through the devastating consequences of a highly transmissible coronavirus. While the pandemic it caused is unprecedented by many measures, the novel coronavirus that causes Covid-19 is just one of many SARS-related coronaviruses lurking among wildlife in some regions of the world, many of which could theoretically jump to human populations under the right conditions.
Figuring out what those conditions are is an urgent priority, and scientists have made a lot of progress on that front. They’ve learned, for example, that when forests get fragmented by deforestation or roads, it increases the likelihood of a virus “spilling over” from animal to human. What’s more of a mystery is where, exactly, those conditions come together to create the highest risk for the next coronavirus emergence.
A new analysis, published Monday in the journal Nature Food, begins to answer that important question — specifically, by pinpointing where another coronavirus could jump to humans from horseshoe bats, which are known to carry SARS-related coronaviruses. By combining data on horseshoe bat habitats, land-use change, human population density, and other factors known to increase the risk of spillover, the researchers produced a map of “hot spots” in Asia and Europe where the risk is highest….’
