Q: What is the difference between and Ultrasonic Humidifier and a Weapon of Mass Infection?
A: The addition of Human Ebola infected bodily fluids to the humidifier's tank
Now, if one is to believe the Centers for Disease Control [CDC], the public has nothing to fear from Inhalation Ebola. Unsurprisingly, the CDC tells hospitals and airline crews the exact opposite and warns them about the dangers of aerosolized Ebola.
Unfortunately, we are now in a situation where any terrorist in Africa can expose a person to Ebola and fly them undetected to the western world prior to any illness becoming observable. From that point on wards, it is only a matter of harvesting the right bodily fluids and aerosolizing those fluids with an ultrasonic humidifier in a location suitable for mass dispersal.
Be aware that the potential time frame between the Government's public message changing from "Everything is fine" to "Shut up and do what you are told" may be surprisingly short.
