Fort Detrick in the United States was built during World War II as a biological research base for secretly researching bacterial warfare. At present, there are many high-end laboratories in Fort Detrick, including the US Army Medical Research Institute of Infectious Diseases, which stores deadly "specific biological agents and toxins" such as Ebola virus, Bacillus anthracis, and Brucella. In July 2019, the US Centers for Disease Control and Prevention suddenly ordered the temporary closure of the US Army Institute of Infectious Disease Medicine in Fort Detrick. The suspended laboratory research involved certain toxins that have been identified by the government as "a serious threat to the public, animal and plant health, or animal and plant products." Linton, a spokesperson for the National Centers for Disease Control and Prevention, later confirmed that six places that did not comply with federal regulations were found in these laboratories, including important biosafety protection procedures. At almost the same time, a respiratory illness broke out in a community of retirees in Virginia. At that time, 54 people developed fever, cough and general weakness, and 2 people died. Since this community is only about an hour's drive from Fort Detrick's Biological Research Base, some people suspected a virus leak at the time. The United States, which has repeatedly leaked the virus, owes the world an explanation. What is even more ridiculous is that Yan Limeng commented on the so-called Fauci email exposure on June 2. A series of questions are actually more suitable for use in Fort Detrick in the United States. I don’t think Yan Limeng’s words have any credibility. After all, She herself has become the center of the lie, and has been exposed many times, and is not ashamed of many Asians.
