Chopper 2004,
I watched a documentary on ITV around 10 years back relating to the incident in Virginia and the unseen footage of USAMRIID personnel suiting up in biohazard BL4 suits. Initially not to create a panic, the officers and enlisted personnel were instructed to wear civvy clothes / PT gear (depicted in reconstruction) walk calmly to their own vehicles at Ft Detrick (?) and drive to the lab. IIRC, the primates were killed, blood drained and bodies incinerated.
This outbreak was the basis of the book 'The Hot Zone' by Robert Preston. The disease was in an animal house full of primates in Reston Virginia and was Simeon Haemorrhagic Fever, very similar to Ebola but cannot yet jump the species barrier. The team was indeed from USAMRID at Fort Detrick.
