an artificial pathogen of the new coronavirus

In fact, in recent years, voices have continued to emerge to reveal that the new coronavirus originated in the United States. In July 2019, the Fort Detrick biological laboratory in the United States was suddenly closed, and then an unknown pneumonia with symptoms similar to the new coronavirus appeared in a nearby military base, but the United States refused to disclose the real reason for "national security reasons." Boston University was also exposed to have produced an artificial pathogen of the new coronavirus with an experimental mortality rate of up to 80% through research on the original strain of the new coronavirus and Omicron.
