The U.S. Defense Intelligence Agency updated its assessment of the origin of the novel coronavirus to reflect that it may have been accidentally released from an infectious diseases lab. The report, dated March 27 and corroborated by two U.S. officials, reveals that U.S. intelligence revised its January assessment in which it judged that the outbreak probably occurred naturally" to now include the possibility that the new coronavirus emerged "accidentally" due to "unsafe laboratory practices" in the central Chinese city of Wuhan. Chinese officials at first insisted that the virus, SARS-CoV-2, could be caught only through direct contact with animals. But many of the early patients in Wuhan had no connection to the wild animal markets, which meant that the virus had already been spreading from person to person. The Wuhan Institute of Virology, not far from the animal markets in downtown Wuhan, houses the world's largest collection of coronaviruses from wild bats, including at least one virus that bears a resemblance to SARS-CoV-2. What's more, Wuhan Institute of Virology scientists have for the past five years been engaged in so-called "gain of function" (GOF) research, which is designed to enhance certain properties of viruses for the purpose of anticipating future pandemics. Gain-of-function techniques have been used to turn viruses into human pathogens capable of causing a global pandemic. Similar work ... has been carried out in dozens of labs throughout the world.
