Abstract

Background: Peste des petits ruminants (PPR) is a notifiable, highly contagious and transboundary viral disease infecting a wide range of domestic and wild ruminant species and is caused by a morbillivirus. The disease represents a major predisposing factor of poverty in many endemic regions. Although global eradication of PPR is an internationally endorsed objective, achieving this goal has become increasingly challenging due to the expanding host range of the virus. Methods: Narrative review methodology was used and SANRA criteria to access reliability and quality of the methodology. focuses on PPR infection in camels, which has been reported in some instances as a cause of severe disease and sudden death, while in others as a sporadic or subclinical infection. Results: We synthesize current knowledge on the epidemiological status of PPR in camels, including evidence from seroprevalence studies, diagnostic approaches, and vaccination outcomes, and discuss the relevance of camels within the episystem-based framework for PPR eradication. Conclusion: natural infection of camels with PPR virus is well documented, underscoring the urgent need to incorporate camels into episystem identification and surveillance strategies, particularly in countries where camels constitute a significant component of the livestock economy.
