In 2009, scientists at the California Academy of Sciences Steinhart Aquarium discovered some of the snakes suffering from a strange illness that caused them to stare off into space, appear like they were drunk and even tie themselves into knots they could not escape. Other serious symptoms included the buildup of proteins, susceptibility to secondary bacterial infections and body wasting. This mysterious illness posed a big problem for captive snakes like boa constrictors and pythons because it can rapidly spread among animals. Animals with symptoms of the disease are therefore killed to help prevent the spread of this fatal illness.
More recently, researchers from the University of California San Francisco sequenced the genome of a healthy boa constrictor and compared the sequence to that of sick animals using microarray technology. They discovered that the culprit was a type of arenavirus distantly related to viruses that cause Ebola in humans. Until now, it was not known that an arenavirus could infect reptiles.

Arenaviruses do not cause Ebola. EBOV is a filovirus.
Yes, that is true. Ebola is a filovirus whereas this newly discovered snake virus is closely related to an arenavirus. What I forgot to mention was that the snake virus also had a gene that is related to Ebola. Therefore, it appears that an arenavirus and filovirus might have shared genes to create this unique snake virus. It is also possible that the snake virus is an ancestor of the modern arena- and filoviruses.
Its crazy how how every species has it own disease Snakes
