Your making it sound like this shit is hard to catch as aids, I'm not buying it.
Granted maybe the tampon point is an exaggeration, but I think its alot easier than you believe.
just look at all the docs catching the shit.
It is blood born purely, but there is some speculation that it can live in an aerosolized mist for about 2 minutes. Allowing for inhalation. Now it still needs to find an open wound of some type. Docs typically catch it because they are treating the sick with needles and doing autopsies on the dead, as well as handling the dead.
People who die of Ebola and all hommorhagic fevers typically do so in a hellish way, frequently sloughing off their entire GI tract and shitting it out in a gout of viral blood, bleeding out immediately. The hospital wards that these doctors live and work for 12 hours a day are literally worse than a charnel house, floors awash is viral blood. That's how they catch it. That is not practical for a bioweapon: to require 3" of viral blood on the floor.
