Just a virus ? How possible is it that a virus borne out of eating animals like bat becomes airborne, the best conspiracy to date is that this is a bio warfare testing gone wrong for China. Why would China need to fumigate a whole city for a virus which they say it's just a flu by the way.

Airborne transmission here means one can get it via inhalation of aerosols from infected persons.
The same applies to other infections like Tuberculosis, SARS, Ebola, Lassa fever, flu, etc.
If you say the 2019nCoV is bio engineered just because it is said to have originated from animals, then, how about the lassa fever that has been with us? It also originated from an animal(rats), and still has aerosols as one of its modes of transmission.
You can get it, just like the coronavirus, by eating the rats(bats in case of coronavirus) or inhaling aerosols from infected persons or droplets from the rats themselves.

So, stop drawing up conspiracy theories(I think that's what Africans are good at) about things you do not understand, and join the world to look for a solution.
