This photograph shows suspected Ebola patient, Peace Corps volunteer, Del Conn, as he was being moved from a plane in Pretoria, South Africa, during the Zaire outbreak of 1976. Mr. Conn, shown here lying inside a rigged plastic isolator, became ill with Ebola-like symptoms while working on the Yambuku survey effort. Worried that Conn was infected with the deadly virus, medical evacuation of the patient from Yambuku to South Africa was ordered. Evacuation of the patient took some time, for it was feared that such exposure of the newly discovered Ebola virus could facilitate its spread locally, as well as internationally. The patient was later treated at an Infectious Disease Hospital associated with the University of Witwatersrand in Johannesburg, South Africa. Thankfully, multiple laboratory tests showed that there was no evidence of the Ebola virus.
