In October of l989, macaque monkeys, housed at the Reston Primate
Quarantine Unit in Virginia, began dying from a mysterious disease at an
alarming rate. The monkeys,imported from the Phillipines, were to be sold
as labratory animals. Twenty-nine of a shipment of one hundred died within
a month. Dan Dalgard, the veterinarian who cared for the monkeys, feared
they were dying from Simian Hemorrhagic Fever, a disease lethal to monkeys
but harmless to humans. Dr. Dalgard decided to enlist the aid ot the
United States Army Medical Research Institue of Infectious Diseases to
help diagnose the case.
