Dear All,
 
I am a former consultant with the GREP Secretariat and received my invitation to this e-conference with a lot of enthusiasm. Unfortunately I got lost in the process due to the fact that where I live in Cameroon the internet connection is a nightmare. However, whenever I can contribute I shall come in. I am quite happy to see all the valuable inputs and also amazed at the rate at which we are learning from this e-conference – thanks to the organizers. 
 
In Cameroon, as in other African countries, small ruminants (sheep and goats) contribute a substantial proportion of the nation's meat supply, and in these animals PPR is considered the most important single cause of morbidity and mortality. The eradication of PPR is proposed and justified based on the success of the earlier Rinderpest eradication campaign. Given the similarities between the two diseases, this seems quite logical.  Going from the question arising from certain quarters whether it is really economically necessary to try to eradicate PPR from especially PPR-endemic developing countries, I have the privilege of sharing some small experience from Cameroon, in the Central African Region from a study carried out by Dr Awa D.N. and others and dwelt on the economics of prophylaxis against PPR and gastrointestinal helminthosis in small ruminants in the north of Cameroon. For this study data on reproduction and mortality were collected over one
 year from 5100 sheep and 13,300 goats in treated and control flocks. The treated animals received vaccination against PPR and anthelmintics twice a year. Productivity parameters (fecundity and mortality rates) obtained with and without prophylaxis were fitted into a benefit-cost economic analysis model and run for project lifespans varying from one to five years. At a 7% discount rate, the overall benefits for a project lifespan of five years were estimated at over 15 million FCFA and 11 million FCFA for sheep and goats, respectively. The benefit-cost ratio ranged from 2.26 to 3.27 in goats and 3.01 to 4.23 in sheep, depending on the project lifespan. It was concluded that PPR and gastrointestinal helminthosis are important causes of economic losses in small ruminants in Cameroon. A national or even a regional vaccination campaign against PPR and strategic anthelmintic treatment of small ruminants were thus recommended.
