It is not transmitted from lung to lung, but can be transferred from a persons touch, for example, then it enters the lung.
So Louie the fly might land on the body of a heavily infected person and carry it to someone else.  just saying.

Leon,
It's transferred via droplets.. ie: Infected person coughs or sneezes on or near you or, coughs or sneezes into their hand then touches you & then you touch your nose, mouth or eyes with that body part. You cannot get infected simply by someone with it touching you.. the only way Louie the fly will be capable of transferring it to you is for it to land in the droplets coughed up by an infected person & then landing on you, transferring a droplet which is then subsequently transferred by you to your eyes, mouth or nose.. this applies to catching it in any way.. the virus on a surface came from someone coughing/sneezing/spitting either into their hands then transferring it to the surface or the above directly onto the surface... then you coming into contact with it & tranferring it to your mouth, nose or eyes...
This is why we have social distancing at 1.5m.. basically, the droplets from someones cough/sneeze will fall before they reach you at that range. This is why we are emphasising hand hygiene so much... good ol soap & hot water will kill the virus, in the absence of soap & hot water, alcohol (at least 65% proof) based hand sanitiser will do the trick. This is why health officials are advocating cleaning with commercial grade disinfectant or bleach products for surfaces, again it will kill the virus if done properly.
Also, whilst not publicised quite as much, health experts are advocating that you should minimise (or completely avoid) touching your face as it is the eyes, nose & mouth & only those points that are the entry point for the virus.. avoiding touching your face isa actually harder to do than you might think...
So, whilst your scenario of Louie the fly passing on the virus to you is not entirely impossible, the amount of 'what ifs' that would have to line up within a timeframe of about 15 minutes, one would venture the likelihood is pretty minimal to negligible...
Note, these are not my own thoughts on transmission, the information on how the virus is transmitted is freely available on the AU Govt Covid19 website & numerous legitimate medical websites that discuss precisely how the virus is transmitted from one human to another.
