A seven-month-old male leopard succumbed to Canine Distemper Virus (CDV) in Kalesar National Park, Yamunanagar district, after a brief illness. The leopard was rescued by the Wildlife Department on June 29 from near Sahzadwala village but died en route to the hospital.
Postmortem reveals multiple organ failure
The postmortem, conducted on June 30 at the Chaudhary Surinder Singh Elephant Rehabilitation Centre in Ban Santour, was performed by a team of three veterinary doctors: Dr Vikrant, Dr Prashant Tiwari, and Dr Rahul, under the guidance of senior veterinary expert Dr Sukhbir Nain. Preliminary findings indicated severe damage to the leopard’s liver, heart, kidneys, and intestines. Internal bleeding was found in the intestines, along with serious respiratory complications. Dr Nain stated, “The symptoms suggest infection with CDV.”
Virus transmission and containment
Canine Distemper Virus is highly contagious among wild carnivores and typically spreads through contact with infected domestic dogs or other wild animals. Dr Nain noted that infected animals often isolate themselves, reducing the risk of widespread transmission. Following the postmortem, the carcass was cremated at the Elephant Rescue Center according to protocol to prevent any infection risk. Viscera samples have been sent to a laboratory for detailed analysis to confirm the exact cause of death.
Surveillance intensified
In response to the incident, the Wildlife Department has intensified surveillance in and around Kalesar National Park. Field staff have been directed to remain vigilant and immediately report any sick or injured wild animals to ensure timely rescue and treatment. The death highlights the threat of CDV to wildlife populations and underscores the need for proactive monitoring and intervention.
