While living in Nigeria Dad played a key role in the transit of a mission nurse from Sudan to New York who was suffering from a mysterious and deadly illness, that became known as the Lassa Fever. Pan Am flights from Lagos only flew once a week. While in Lagos she was kept in the “Pest House” an old building with rudimentary medical facilities for infectious disease patients. I remember the family driving home from church and stopping off at the Pest House so he could check in with her and provide IV fluids. Arranging the Pan Am flight was no mean feat. He had to get Pan Am to clear four first class seats so they could create a makeshift isolation ward on the plane. Following protocol for medical evacuations, he was given the form to fill out. One of the screening questions was whether the patient had a “known communicable disease”. He paused a moment and then checked “no”, muttering under his breath that it was an “unknown communicable disease”.
