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.
