Global land-use changes are creating "hot spots" for potential emergence of new coronaviruses
Global land-use changes -- including forest fragmentation, agricultural expansion and concentrated livestock production -- are creating "hot spots" favorable for bats that carry coronaviruses and where conditions are ripe for the diseases to jump from bats to humans, finds an analysis published this week by researchers at the University of California, Berkeley, the Politecnico di Milano (Polytechnic University of Milan) and Massey University of New Zealand.
While the exact origins of the SARS-CoV-2 virus remain unclear, scientists believe that the disease likely emerged when a virus that infects horseshoe bats was able to jump to humans, either directly through wildlife-to-human contact, or indirectly by first infecting an intermediate animal host, such as the pangolin, sometimes known as the scaly anteater.
