I think there's some really invalid assumptions going on with the reasoning here. I don't have an exact answer, but I can challenge these assumptions. You don't leave a "virus cloud path" behind you. It just follows the wind in random directions and quickly disperses within a few feet to concentrations that are safe (studies have shown that viral load of initial exposure is a significant factor in disease severity). Below a certain concentration, your immune system will just handle the few viral cells which landed on you. I would challenge the 3ft vs 10ft thing as actually being a big stretch. I think further research is needed to say anything about that for sure, but keep in mind that beyond some certain distance, probably around 10 feet, distance stops mattering. In some sense, 100 ft is the same as 1000 ft. I would guess the threshold where distance stops mattering is somewhere between 6ft and 10ft, and realistically 10ft should be safe.

> Below a certain concentration, your immune system will just handle the few viral cells which landed on you. We don't know what a "low viral load" means for infectiousness. Yes, maybe you fight off the virus successfully after being exposed to a low amount of virus. But perhaps you are infectious for 2 days and infect 2 people. Who each infect 2 people. Who each infect 2 people. Who each infect 2 people. I shouldn't have to explain this here... 2 4 8 16 32 64 128 256 512 1024 2048 4096 8192 16,384 32,768 65,536 131,072 262,144 524,288 1,048,576

  > We don't know what a "low viral load" means for infectiousness. One way the phrase is used refers to severity being dependent on initial viral load. That's what I think you're talking about. Someone can have a mild infection or asymptomatic but still be contagious. What jsharf is referring to is that below the infectious dose, exposure to the virus doesn't necessarily develop into an infection.
