The existence of pathogenic sprays and capsules is controversial and under debate.

“What the Sovs did was invent micron sized capsules into which _any_ pathogen could be inserted. That solves the transmission problem. The capsule protects the contents for a few days, after which normal environments break them down. The capsules float in the air like dust and as few as ten to twenty capsules are enough to cause infection. The capsule approach also solves the runaway plague problem since you don't need a highly infectious agent. The capsules allow the user to manufacture what amounts to a war gas with _tremendous_ toxicity, good persistence and no residual effect.
With this kind of weapon, antidotes and vaccines are nice but not essential. You can dose an area, wait out the decay period for the delivery capsules and wait for all the cases to develop, then move in with impunity.
According to Alibek, the FSU manufactured encapsulated Marburg in ten ton lots along with other pathogens. The Russians are still doing it. I'm afraid Eric's GodSat isn't that puissant after all.”
