The strain Ebola-Reston is the airborne strain of ebola. It was discovered in Reston, VA in monkeys that were imported from Africa. The cause for alarm was that anytime monkeys come in from africa, they are quarantined so that any monkeys with potentially fatal diseases like Ebola-Zaire die off. They are kept in individual cages. The reason the Ebola-Reston was discovered was because all the monkeys in the facility started dying of some sort of hemorhagic fever. They were afraid it was an airborne strain of Ebola or Lassa Fever that could infect humans. It turned out that, though it seemed to be identical to Ebola-Zaire, it caused no infection in humans. hence the new strain Ebola-Reston
