" One animal died and, after it tested positive for Reston virus, forty-nine others housed in the same room were “euthanized” as a precaution. (Most of those, tested posthumously, were negative.) Ten employees who had helped unload and handle the monkeys were also screened for infection, and they also tested negative, but none of them were euthanized. "
