According to the official narrative, a new strain of highly infectious and deadly coronavirus was discovered in Wuhan, China at the end of 2019. It was thought to have originated from a wet market in the city where they sell bats amongst other local delicacies.
The fact that there happened to be a Level 4 biochemical laboratory within a short distance away from the market and that they were experimenting on a coronavirus carried by bats is just a coincidence.
From Wuhan, this virus was then carried by six infected air travellers who transmitted it to the rest of the world in no time.
The World Health Organization declared the outbreak a Public Health Emergency of International Concern on 30 January 2020, and a pandemic on 11 March 2020.
