The new coronavirus emerged from the global wildlife trade – and may be devastating enough to end it

COVID-19 is one of countless emerging infectious diseases that are zoonotic, meaning they originate in animals. About 75% of emerging infectious diseases are zoonotic, accounting for billions of illnesses and millions of deaths annually across the globe.

When these diseases spill over to humans, the cause frequently is human behaviors, including habitat destruction and the multibillion-dollar international wildlife trade—the latter being the suspected source of the novel coronavirus.

The COVID-19 pandemic has forced governments to impose severe restrictions, such as social distancing, that will have massive economic costs. But there has been less discussion about identifying and changing behaviors that contribute to the emergence of zoonotic diseases. As a conservation biologist, I believe this outbreak demonstrates the urgent need to end the global wildlife trade.

Markets for disease

As many Americans now know, the COVID-19 coronavirus is one of a family of coronaviruses commonly found in bats. It is suspected to have passed through a mammal, perhaps pangolins – the most-trafficked animal on the planet—before jumping to humans.

The virus's spillover to humans is believed to have occurred in a so-called wet market in China. At these markets, live, wild-caught animals, farm-raised wild species and livestock frequently intermingle in conditions that are unsanitary and highly stressful for the animals. These circumstances are ripe for infection and spillover.
