The report describe an unusual mortality event involving 26 sperm whales occurred in the Mediterranean from Nov 2018 through July 2019, counting for about 2% of the Mediterranean SW subpopulation. Main findings were Cetacean Morbillivirus (CeMV) infection, marine debris ingestion and entanglement. Due to epidemiological and molecular evidences CeMV was considered as a relevant factor in the mortality while marine debris and entanglement as an incidental findings. Other human related activities were excluded due to absence of spatial and temporal association.
