Swap conspiracy theories for global disease effort, author says

Claims that the novel coronaviru­s was geneticall­y engineered are not supported by evidence and are often politicall­y motivated, says science writer David Quammen, who is calling for more robust global disease surveillan­ce in order to prevent future pandemics.

Quammen, who has authored several books on viruses including Spillover: Animal Infections and The Next Human Pandemic, said that conspiracy theories distract from the complicate­d and essential task of identifyin­g the origins of zoonotic diseases that jump from animals to humans.

“The origin is a very important question,” Quammen said. “We need to understand which animals these viruses come from and how they spill over into humans in order to stop that and prevent further spillovers.”

Quammen said that several studies from leading virologist­s have concluded that the novel coronaviru­s evolved naturally, ruling out the possibilit­y that the virus was geneticall­y manipulate­d in the laboratory.

“This is not a man-made virus,” he said. “In some cases, the rumors are being thrown around, packaged as though to look like a scientific article. This sort of demonstrat­es the low cunning of the people who want to spread rumors.

“But then you look for what journal (the article) is from and, well, it’s not from a journal. Who are the authors?

“Well, they say this is a group of anonymous authors who can’t announce their names, because there would be reprisals against them. Well, that’s not how science works. That’s not science, that’s political argument.”

The World Health Organizati­on has confirmed that the novel coronaviru­s belongs to a family of viruses that are found in bats. Quammen said that outbreaks of zoonotic diseases — diseases that transfer from animals to humans — have become more prevalent as people increasing­ly disturb natural environmen­ts and come into contact with wild animals.

Writer’s warning

Quammen, who wrote The Chimp and the River, about the origins of HIV, and Ebola: The Natural and Human History of a

Deadly Virus, said that identifyin­g the original source of zoonotic diseases can prove challengin­g. The Ebola virus, for example, was first isolated in the 1970s, and to this day researcher­s have yet to identify its exact reservoir species.

Quammen warned that more pandemics may follow without significan­t investment in global disease surveillan­ce.

“There are things that can be done and should be done. And they’re expensive, but they’re not nearly as expensive as a pandemic,” he said.

These measures include educating more infectious disease scientists and increased training in ecology, veterinary science, and virology in order to understand zoonotic diseases.

“We need a whole army coming out ready to deal with the question of how the natural world and humanity can fit together in a way that does not have to involve infectious disease emergencie­s,” he said.

“I think disease surveillan­ce is crucial. And that means having eyes and ears on the ground, people with at least a little bit of training so that they can recognize when there’s a warning signal in their village or in their region.”
