Dear Colleagues I do not believe the"spread" of PPR in Africa is due to improved surveillance! We had pretty good seroepidemiological data on wildlife, which is NOT vaccinated, showing probable presence of the infection spill over in wildlife of West & Central Africa & Ethiopia over the last 30 years but equally good evidence that there was no infection in wildlife south of Sudan and Ethiopia up to 2003. After this there has been evidence of antibody conversion at the population level in Ugandan buffalo in 2003-4 which was reported from CIRAD and through IBAR in 2004 and we are now working in East Africa through the IUEPPR project to establish if this trend has continued. Negative baselines exist for Kenya and Tanzania. By revisiting some of these populations we will know how recent and persistent infection has been further south - spatially and temporally. The exact reason for this is speculative but we would have to consider reduced immunity, in susceptible species, after cessation of RP vaccination as a strong possibility or extraordinary coincidence! I also agree that increasing animal numbers & densities, movements etc probably have played a role in this. Much to learn.

I think you will be in better position to answer as working on PPR while passing through all of RP campaign. To me resurgence of PPR is only due to its importance and awareness in scientific as well as farmer community. RP vaccination might have its role in Africa but talking of South Asia and surroundings, disease was present but not being reported with this intensity as today. Also, most of the workers on RP has turned their tables towards PPR.
