T

he Riau Natural Resources Conservation Agency (BBKSDA) has revealed that the death of an 18-month-old Sumatran elephant named Laila was due to an elephant endotheliotropic herpes virus (EEHV) infection.

“Based on a laboratory examination of samples of tissues and organs conducted by Medika Satwa Laboratoris in Bogor, West Java, the cause of Laila’s death was EEHV infection,” he said on Monday.
