Rising temperatures and climate risks are expected to contribute to the spread of infectious diseases, including viruses. Which worries some scientists. Some people think we're done with pandemic stories. But we risk having many more of them. I know I sound like a bird of ill omen when I say that! Hervé Fleury, virologist and professor emeritus at the CNRS and the University of Bordeaux, does not mince words. For him, the observation is clear: the loss of land in connection with the Covid-19 pandemic in no way marks the end of the danger posed by viruses. According to him, humanity would even have a good chance of encountering it again in the coming years. "There are many factors: changes in ecosystems, deforestation, increase in the number of people, resettlement of populations... Even the airplane, which is a very important way of transmitting the virus," he states. searcher. (Timothée Barnaud)
