Between late 2011 and 2013, three men in succession — aged 63, 62 and 72 years — from the state of Saxony-Anhalt, Germany, suffered a progressive encephalitis or meningoencephalitis that led to death within 2 to 4 months after the onset of clinical symptoms. The clinical course was characterized by fever, shivers, or both; progressive psychomotor slowing; confusion; unsteady gait; myoclonus, ocular paresis, or both; and finally, coma. All three were breeders of variegated squirrels, a tree squirrel that is endemic in Central America from south Chiapas, Mexico, to Panama. They were friends, had met privately on a regular basis, and had exchanged their squirrel-breeding pairs on multiple occasions. At least two of the men had been scratched by their squirrels in the past; one had been bitten.
