The bat coronavirus grant provided the EcoHealth Alliance with a total of $3.1 million, including $599,000 that the Wuhan Institute of Virology used in part to identify and alter bat coronaviruses likely to infect humans. Even before the pandemic, many scientists were concerned about the potential dangers associated with such experiments. The grant proposal acknowledges some of those dangers: “Fieldwork involves the highest risk of exposure to SARS or other CoVs, while working in caves with high bat density overhead and the potential for fecal dust to be inhaled.”
Alina Chan, a molecular biologist at the Broad Institute, said the documents show that the EcoHealth Alliance has reason to take the lab leak theory seriously. “In this proposal, they actually point out that they know how risky this work is. They keep talking about people potentially getting bitten — and they kept records of everyone who got bitten,” Chan said. “Does EcoHealth have those records? And if not, how can they possibly rule out a research-related accident?”
