Dear colleagues,

To my point of view in answer to Dr Ithondeka's question: A key issue to 
address is why PPR resurgence now? Is it true that rinderpest 
vaccination suppressed PPR?

theses reasons might be invoked: 1) long-time negligence or 
inattentiveness to the small-ruminant health sector in all the countries 
now enzootic for the disease, leading to a lack of performing 
diagnostic; 2) increasing size and mobility of small-ruminant 
populations; 3) cessation of rinderpest circulation, which is generally 
mild in small ruminants and which the cross-reactive antibodies allowed 
for an additional gain in protection.

Among those points N°2 is the most important.

Best regards
Geneviève
