Trypanosoma evansi T evansi the protozoan parasitic cause of camel trypanosomosis Surra constitutes one of the major veterinary problems worldwide An infectious disease model of camel trypanosomosis Surra was adopted from one developed for buffalo and applied to study the impact of T evansi infection on camel production The model contained deterministic and stochastic components and the seroprevalence based on a survey conducted in Somaliland in 2011 and 2012 to simulate and estimate the economic benefits of four different control options against T evansi infection in camels 1 2 3 and 4 regimens The mean benefit per animal of controlling surra was calculated at US354 the treatment of all camels biannually US426 the monthly targeted treatment of clinically sick camels and US287 biannual targeted treatment of seropositive camels respectively compared with US137 for untreated camels Consequently the model predicted that the total net benefit loss to a camel herd or village that was not applying the recommended effective surra control strategy was US115605 694 billion shilling per annumThe authors thanked the Ministry of livestock of Somaliland for facilitating the study We would like to acknowledge the cooperation of pastoralist and field technical staff for their considerable support and help We are grateful for the technical support by Dr Mohamed F Dirie and the Somali Animal Health Services Project Somaliland office who willingly collaborated in the implementation of this study We also wish to thank Sheikh Technical Veterinary School for their technical assistance Murdoch University and the International Foundation for Science IFS funded this study Financial supports from IFS grant number B/5121
