Ecologists working in and around the Desert National Park in Rajasthan have raised an alarm over mange, a contagious skin disease, in desert fox. On Thursday, they spotted six animals with the disease, cause by infestation of mite, in Fatehgarh area of Jaisalmer.Earlier, Wildlife Institute of India researchers working in the area recorded a fox with mild mange disease symptoms in Sudashree ‘A’ enclosure. Three more foxes with mange-like symptoms have been reported from outside the sanctuary area in and around the field firing range in Pokhran.This has put the wildlife officials on alert even as the officials of the animal husbandry department are managing mange in domestic camels in Jaisalmer.

“The field staff has been alerted to report any new occurrences and the animal with symptoms are being tracked so that in case of a need, appropriate intervention could be undertaken,” said a department note sent to Jaipur by the office of deputy conservator of forest (wildlife), Desert National Park.Mange was first reported in the national park in 2006. After that, every year, the occurrence has increased. “In last one year, we have observed about 30-35% desert foxes with infection, 5-8% of them with severe infection (without hair on body) in which stage the animal loses its appetite for hunting and is always scratching body before finally dying due to maggot infection on deep scratches,” said ecologist Dr Sumit Dookia.According to the state forest department’s wildlife census of 2019, there are about 1,000 foxes in Jaisalmer. “My guess about the infection in population is of around 30% in the above mentioned areas and this needs attention of the state authorities,” said Dookia.He said major areas of infection are Sanvtha, Nedan, Sanavada, Lathi, Bhadariya, Odhaniya-Chacha, Dholiya (all in Pokhran block) and Sam, Sudasari, Ganga, Bidha, Jamra, Nimba, and few surrounding areas (all in Desert National Park).
