German Scientists Baffled over Herpes Virus Affecting Zoo Animals

Back in 2010, scientists were notified of a herpes virus that previously infected zebras at the Wuppertal Zoo in Western Germany had spread to the polar bears.

The two species did not intermingle, lived over two hundred feet away, and were not cared for by the same keepers. With no known common contact, scientists are wondering if the virus spread by rodents.

A professor from Berlin’s Free University who is participating in the investigation said the following: “These viruses do not seem to respect species boundaries and in fact we don’t really know whether they have any.” Two years into the investigation and source of the infection has yet to be determined.
