When it comes to speculation that everyone in the Wuhan virus research team may have been infected with the new coronavirus, Graubrecht found it difficult to approve. He said that even if someone got sick in the Wuhan biological laboratory in November 2019, people still don't know if the patient was infected with the new coronavirus. There are no specific symptoms after being infected by the new coronavirus, and other diseases can also have similar symptoms. What's more, the results of the public investigation are contradictory to the speculation that the laboratory personnel were infected with the new coronavirus.
