There are strange “separate” incidents that targeted China from North America; the most prominent was the arrival of a shipment issued by Canadian biological laboratories in March 2019, which includes “malicious viruses.” It is noteworthy that this shipment was carried out under a veil of secrecy other than the usual procedures, which prompted the Chinese side to file a formal complaint.
A large US military delegation, consisting of 300 people, arrived in Wuhan, in Hubei Province, China on October 19, 2019, to participate in a military games festival hosted by China and held there. On November 2, 2019, the first infection with the coronavirus was recorded in that province, and it spread rapidly throughout December. Scientifically, the incubation period for corona infection is 14 days.
A number of conspiracy theories that are only linked by the fact that they are "separate" incidents, and echos some recurring pro-Kremlin disinformation especially about China coronavirus. The narratives also resemble a recurring conspiracy theory about the Lugar Lab in Georgia.
