Second elephant dies from Herpesvirus at Adventure Zoo Emmen
A second young elephant has died at Wildlands Adventure Zoo Emmen within five days, both likely due to the highly lethal elephant endotheliotropic herpesvirus (EEHV). The deaths have left the zoo’s elephant herd in mourning and under increased observation by their caretakers.
The latest death occurred Wednesday evening when Ka Yan, a 3-year-old male, succumbed to the virus. Ka Yan had shown symptoms earlier in the day, similar to those seen in Nagarr, a calf that died on Saturday. Despite immediate intervention, the young elephant could not be saved.
Veterinary experts at Utrecht University’s Faculty of Veterinary Medicine confirmed that Nagarr’s death was caused by EEHV. Preliminary assessments suggest Ka Yan was also infected with the virus.
EEHV poses a significant threat to young elephants, whose immune systems are not yet fully developed. The virus is known for its rapid progression, often leading to death within hours or days after symptoms appear.
“Ka Yan started showing signs of distress in the morning,” the zoo said in a statement. “Despite prompt action by our team, we couldn’t save him.”
The zoo's caretakers have isolated the herd’s two remaining young males, both six years old, to minimize stress and closely monitor their health.
The deaths have deeply impacted not only the elephant herd but also the zoo’s staff and visitors. After Ka Yan’s passing, the herd was allowed to mourn and say their goodbyes, a practice believed to help elephants process loss.
“This tragedy affects everyone at Wildlands deeply,” the zoo stated. “We are doing everything possible to support the remaining elephants during this difficult time.”
The EEHV virus is one of the leading causes of death among young elephants, both in captivity and in the wild. Earlier this month, on November 4, a young African elephant named Bumi died of EEHV at Ouwehands Zoo in Rhenen. Bumi became lethargic in the afternoon and passed away within hours.
There is currently no vaccine or definitive treatment for EEHV. Scientists around the world are collaborating to develop preventive measures or effective treatments. Wildlands has been actively involved in these efforts, partnering with Utrecht University on research aimed at combating the virus.
