Nautilus Magazine: The Man Who Saw the Pandemic Coming

Typically the preparation of the animal is where you have exposure. By the time it’s cooked and prepared, the virus would have been dead. It’s more common that transmission is through the animal shedding or people slaughtering the animal, when they’re exposed to bodily fluids, blood, and secretions. With the avian influenza from poultry, a lot of the exposure and infections go back to the preparation of chicken for cooking. In Egypt, for instance, when you look at who was infected, more common than not it was a woman, directly responsible for slaughtering and preparing the animal. [...]

Certainly. We’ve been able to identify bats as reservoirs for coronaviruses and documented specific bat populations as reservoirs for Ebola virus. We want to understand how each of these bats operate within an ecosystem. Do they have certain behaviors and practices that either keep them remote from or proximal to human populations? The bat population in which we isolated the Ebola virus in West Africa was a species of bat that also tends to co-roost within human housing, so it elevates the opportunity for spillover. [...]

Yes. EcoHealth Alliance, an NGO, and others, looked at all reported outbreaks since 1940. They came to a fairly solid conclusion that we’re looking at an elevation of spillover events two to three times more than what we saw 40 years earlier. That continues to increase, driven by the huge increase in the human population and our expansion into wildlife areas. The single biggest predictor of spillover events is land-use change—more land going to agriculture and more specifically to livestock production. [...]

Oh, sure. It was predictable. It’s like if you had no traffic laws and were constantly finding pedestrians getting whacked by cars as they crossed the street. Is that surprising? No. All you need to do is to better manage how we set up crosswalks, how we establish traffic rules and regulations. We’re not doing that. We’re not establishing the kind of safe practices that will minimize the opportunity for spillover. If we better understood where these viruses are circulating and understood that ecology, we would have the potential to disrupt and minimize the risk of spillover.
