This photograph shows a cardboard box, which contained a blood serum sample from an American missionary nurse, Lily Pinneo, which was collected after she had recovered years before, from a Lassa fever viral infection. Ms. Pinneo contracted the virus while in northern Nigeria, in 1969. This serum was obtained in hopes that her antibodies would help in the recovery of those infected with the Lassa virus, and save them from this deadly hemorrhagic disease. This serum was shipped to Rhodesia, in 1975, during a mysterious hemorrhagic disease outbreak, but it was later determined by EIS Officer, Lyle Conrad, MD, that the Marburg virus was responsible for that disease. Laboratorian Frederick A. Murphy, DMV, PhD, later confirmed Dr. Conrad’s findings, by identifying the virus particles through electron microscopy.
