Bhopal, May 2 -- The death of a tigress and her four cubs within 10 days in Madhya Pradesh's congested Kanha Tiger Reserve, one of India's most iconic tiger habitats, were due to Canine Distemper Virus (CDV), forest department officials said on Friday, adding that the preliminary reports have confirmed the same. A senior forest officer said, "Canine Distemper Virus (CDV) has been confirmed. We have begun vaccinating dogs and sanitising forest water bodies and surrounding areas." Kanha reserve deputy field director Prakash Kumar Verma said, "Indications of the virus were found in tests at the School of Wildlife Forensics and Health, Jabalpur. Final reports on water and blood samples are awaited." The 10-year-old tigress T-141 and her year-old cubs died in the Sarhi range of the reserve. Two cubs died on April 21 and 23, a third on April 25. The tigress and another cub, who were suffering of gastrointestinal and respiratory infection, were rescued on April 26 but they succumbed on Wednesday morning. Forest teams are now sanitising the reserve and monitoring wildlife round-the-clock. "Our priority is containment. No symptoms have been detected in other animals so far, so there is no need for panic," the officer said. Kanha is home to about 140 tigers living in an area of 2,000 square kilometers and is among the most crowded feline habitats in the country....
