Endemic in large parts of the world, PPR causes severe damages to animal production and household economies. In 2015, FAO and OIE launched a global eradication program (GCSE) based on vaccination campaigns. The success of GCSE shall depend on the implementation of vaccination campaigns, accounting Edited by: for husbandry practices, mobility and the periodicity of small ruminants’ population Eyal Klement, The Hebrew University of renewal. In Mauritania, PPR outbreaks occur annually despite ongoing annual vaccination Jerusalem, Israel campaigns since 2008. Here, we developed a mathematical model to assess the impact Reviewed by: of four vaccination strategies (including the GSCE one), the importance of their timing of Jonas Johansson Wensman, Swedish University of Agricultural implementation and the usefulness of individual animal identification on the reduction of Sciences, Sweden PPR burden. The model was calibrated on data collected through ad-hoc surveys about Arnab Sen, demographic dynamics, disease impact, and national seroprevalence using Monte Carlo Indian Council of Agricultural Research, India Markov Chain procedure.
