Currently there are a number of theories that have been proposed and widely circulated:
1.This is a natural virus that crossed over from an animal reservoir such as bats/pigs/pangolins and possibly dogs as a result of meat being sold in the notorious Wuhan ‘Wet markets’, this has been seen before in the previous MERS/SARS and Ebola outbreaks.
2. This is an unfortunate mutation of a Coronovirus that occurs naturally within the Human Body and was subsequently transmitted into the community, and goes hand in hand with the animal reservoir theory
3. This is a designer virus manufactured in the State-run Wuhan Institute of Virology and was accidentally released. As recently as 2018 the US State department raised concerns about the Bio-security at the Wuhan Laboratory with the Washington Post stating:
“They (the State Department) warned that sloppy safety protocols for handling contagious viruses in the lab ‘represented a risk of a new SARS-like pandemic.’” (Yes, folks this was in 2018!)
This appears to be the favoured origin of Donald Trump but has not been endorsed by the WHO and the Intelligence group called ‘Five Eyes’ (US, Uk, Australia, New Zealand and Canada) have reported that there is no evidence of this.
4. One last theory is that of Pansmermia, which is the hypothesis that “life exists throughout the Universe, distributed by space dust, meteoroids, asteroids, comets, planetoids, and also by spacecraft carrying unintended contamination by microorganisms.” This theory has long been proposed by the astronomers Professor Chandra Wickramsinghe and the late Fred Hoyle. Wikramsinghe has recently postulated that the passage of the tail of a comet over northern China in October 2019 was the origin of the Coronovirus – Yes folks “The Truth is OUT There” and everything we watched on ‘X Files’ REALLY IS TRUE’.
