Abstract
During November–December 2017, a mass die-off of Guiana dolphins (Sotalia guianensis) began in Rio de Janeiro, Brazil. Molecular and pathologic investigations on 20 animals indicated that cetacean morbillivirus played a major role. Our findings increase the knowledge on health and disease aspects of this endangered species.

During November–December 2017, a mass die-off of Guiana dolphins (Sotalia guianensis) began in Rio de Janeiro, Brazil
Chronic bronchointerstitial pneumonia and multicentric lymphoid depletion observed in most animals are common findings in Cetacean morbillivirus (CeMV)-infected cetaceans, these lesions were considerably overlapped by H. brasiliensis endoparasitosis
