What does it take to prevent a pandemic? Disease dynamics are extremely complex, and there’s no guarantee that they will stop doing what they do best — jumping from animals to humans. Such diseases are able to survive between species (such as SARS and the Plague, which originated in rodents in the medieval era but still exists today) and are nearly impossible to eradicate. With our current level of urbanization and industrial livestock farming, it seems we will always be running a risk of new variants of biological threats. Only if we take animal health and wellness more into consideration, and look at other factors such as our environmental footprint, will we be able to guard ourselves in the future, Robert Peckham, author on infectious disease, tells Bloomberg (watch, runtime: 7:11).
