Wray made the statement last week in a televised interview with Fox News, in response to a question about the origins of the COVID-19 virus. Wray said that, “for quite some time now”, the FBI has “assessed that the origins of the pandemic are most likely a potential lab incident in Wuhan”, a city in central China. Wuhan hosts the Wuhan Institute of Virology, which includes laboratories that specialize on biosecurity and the study of newly emerging infectious diseases. Wray added that Beijing has “been doing its best to try to thwart and obfuscate the work” of the United States in trying to determine the precise origins of the virus.

Late last week, Dr. Maria Van Kerkhove, an infectious disease epidemiologist and the WHO’s technical lead on COVID-19, said the WHO had contacted the United States’ mission to the United Nations in Geneva, Switzerland, to inquire about the information that informs the FBI’s assessment. On Friday, meanwhile, Dr. Tedros called for “any country [with] information about the origins of the pandemic” to come forward. The WHO Director-General went on to say that “it’s essential for that information to be shared with WHO and the international scientific community”.

The WHO also called on China “to be transparent in sharing data and to conduct the necessary investigations and share the results” with the global scientific community, “not so as to apportion blame, but to advance our understanding of how this pandemic started, so we can prevent, prepare for and respond to future epidemics and pandemics”. When asked about the WHO’s own investigation into the origins of COVID-19, Dr. Tedros responded that “all hypotheses on the origins of the virus remain on the table”.

In the meantime, China responded angrily to the FBI director’s comments. Beijing has previously dismissed claims that COVID-19 may have emerged as a result of an accident at a Chinese government-funded lab as a disinformation campaign designed to smear its image and reputation around the world. Last week, Mao Ning, a spokeswoman for China’s Ministry of Foreign Affairs, reacted angrily to allegations that the government of China is responsible for the COVID-19 pandemic. Mao called on the United States to “look to its own biological laboratories scattered across the world when searching for the virus’s source”.
