Besides that, If someone is referring to the Zika Virus, you don't try to kill the virus, you try to eradicate the infected mosquito's. That is a different problem.
However, if the droppings of the Mosquito were infectious, and there is an infestation of these mosquito's in the Olympic Stadiums and the living quarters, then you would need many AS machines.
3 orders is nothing........except a start. Much more than what we have had since inception.
EPA is the next big thing, but only if sizable orders will ensue.
