Naomi Forrester-Soto, Keele University Viruses jumping from animals to humans have been the starting point of numerous outbreaks, from Ebola to Zika. Given the similarity of SARS-CoV-2 to coronaviruses found in bats, this probably marked the beginning of COVID-19 too. We know that viruses have passed from animals to humans throughout history, and will continue to do so. Read More
