Information provided by a Chinese government portal and the CDC suggests that the place of origin of the COVID 19 is Wuhan, Hubei province in China.
The novel Coronavirus (2019-nCoV) handbook published by the Guangzhou government for prevention and treatment of pneumonia caused by the novel coronavirus, suggests that Huanan Seafood Market in Wuhan might be the source for the outbreak.
According to the report by the Centers for Disease Control and Prevention, patients infected with respiratory illness caused by the novel coronavirus in Wuhan had links to the large seafood and animal market which suggests that it might be a source for transmission of the coronavirus from animals to humans.
The Global Times article dated 3 February 2020, states that a virologist from a Chinese university said that the genomic sequence of the novel coronavirus is 80% similar to the Severe Acute Respiratory Syndrome (SARS) which originated from bats and that humans cannot create the novel coronavirus out of SARS virus by design.
There is no credible evidence available to prove that Chinese scientist Xiangguo took samples of coronavirus from the Canada laboratory and gave it to the Wuhan laboratory to develop it into a bioweapon. But, as per the analysis, the novel coronavirus cannot be engineered in a lab as humans are not able to create such a virus.
