For over 2 years, silverback Isano of Agashya group in Rwanda's Volcanoes National Park has been closely monitored for skin lesions around his upper body. In November 2023, he was treated under anesthesia – however, the lesions persisted. While the specific cause is still unknown, Isano has appeared to be in good health aside from the lesions.
A recent field note indicated that the lesions appeared to be healing, confirmed by Gorilla Doctors veterinary intern Emmanuel during a health check on October 28. This past Monday, Dr. Gaspard visited Agashya group to follow-up with Isano.
He reports that the lesions on Isano are healing well! Routine monitoring will continue.
