Emerging diseases like SARS and this new, related coronavirus are coming from “wet markets” – marketplaces that sell terrestrial and aquatic wildlife from around the world for human consumption. Steve Osofsky, professor of wildlife health and health policy at the Cornell College of Veterinary Medicine, says it is time to shut down wet markets for good.

Osofsky says:

“Some of my colleagues have suggested that the type of outbreak we are seeing with this latest coronavirus (a relative of SARS) can be managed by improving hygiene and surveillance in wildlife ‘wet markets’ common in China and other parts of Asia. They suggest that new drugs will come to our rescue.

“At a time when the entire world is increasingly bearing the costs of the global wildlife trade, where billions of dollars of public health emergency costs and the depletion of the world’s wildlife are literally the trade’s primary byproducts, it is time to shut down these markets forever. Full stop. It’s what’s right for public health, for biodiversity conservation, for the global economy, and for socioecological stability. We can no longer ignore the fact that the enormous risks and costs to all of us exceed the benefits flowing to a subset of people involved in this trade, much of which is also, by the way, illegal.”

Gary Whittaker

Professor of Virology

Gary Whittaker, virology expert at the Cornell College of Veterinary Medicine, researches how coronaviruses are a major cause of disease in many animal species and have become increasingly important as human pathogens. He says the coronavirus can enter cells easily, which makes it particularly difficult to control.

Whittaker says:

“All viruses need to gain access into host cells to infect, and how they do this can control disease. Coronaviruses like the one currently causing an outbreak in China are particularly flexible in how they can enter cells, which makes them especially problematic as emerging viruses.

“By analyzing sequence changes between existing and emerging viruses we can model structure and function and use this to predict changes in virus stability, transmission and pathogenesis, and how viruses move between species and cause enhanced disease within a given species.”

Associate Professor of Government

Another obstacle in the battle to control the spread of the coronavirus is access to information from China. Jeremy Wallace, professor of government at Cornell University, researches the ways that China has managed its growing cities to maintain order through environmental, political, economic and social issues connected to urbanization. He says it is important to maintain transparency as the country deals with the potential epidemic.

Wallace says:

“Making predictions about the future course of the novel coronavirus from Wuhan, China is difficult. Figuring out when the virus moved into the human population is hard, especially if most people infected do not experience serious symptoms. However, such assessments are key to understanding its lethality and tracing the rate of growth for a potential epidemic over time.

“While initial reporting appears to have faced obstacles either bureaucratic or political in nature, Beijing seems to have corrected course and being transparent as it deals with this potential crisis.”
