Samples of the suspected SARS virus and influenza were found in Chinese scientists’ luggage arriving in the U.S., according to an unclassified FBI tactical intelligence report obtained by Yahoo News.

In November 2018, U.S. Customs and Border Protection agents at Detroit Metro Airport stopped a Chinese biologist who was carrying three vials labeled “Antibodies” in his luggage. The biologist said a colleague in China “had asked him to deliver the vials to a researcher at a U.S. institute. After examining the vials, however, customs agents came to an alarming conclusion,” Yahoo reported.

“Inspection of the writing on the vials and the stated recipient led inspection personnel to believe the materials contained within the vials may be viable Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS) materials,” the report said.

The report, written by the Chemical and Biological Intelligence Unit of the FBI’s Weapons of Mass Destruction Directorate (WMDD), does not give the name of the Chinese scientist carrying the suspected SARS and MERS samples, or the intended recipient in the U.S. But the FBI concluded that the incident, and two other cases cited in the report, were part of an alarming pattern.

There have been numerous reports that the coronavirus may have emerged from a lab in Wuhan, China. In February, the Chinese Ministry of Science and Technology put out a directive titled: “Instructions on strengthening biosecurity management in microbiology labs that handle advanced viruses like the novel coronavirus.”

It turns out that in all of China there is only one such lab, the New York Post wrote. “And this one is located in the Chinese city of Wuhan that just happens to be . . . the epicenter of the epidemic.”
