Global strategy for the control and eradication of PPR

The OIE and the FAO developed jointly the Global Control and Eradication Strategy of PPR under the Global Framework for the progressive control of Transboundary Animal Diseases (GF-TADs).

The strategy covers three components:

a technical step-wise approach (stage 1 to stage 4) to control and eradicate the disease ;
the strengthening of Veterinary Services in order to be able to carry out the technical component ;
the control of other priority small ruminant diseases together with PPR in view of increasing the impact of the control efforts.

Step-wise approach

The four stages correspond to a combination of decreasing levels of epidemiological risk and increasing levels of prevention and control.

The stages range from stage 1, when the epidemiological situation is being assessed, to stage 4, when the country can provide evidence that there is no virus circulation, and it is ready to apply for the OIE official status of freedom from PPR.

A country is “below stage 1” if there is no epidemiological information available, and “beyond stage 4” if the OIE official status recognition has been concluded.

The strategy provides flexibility for countries to also take the shortcut options, as shown by the arrows in the diagram below.

For example, a country that determines, during stage 1, that there is no PPR virus circulating in the country may move directly to stage 4.

How to assign a country to a stage?

By assessing the following 5 technical elements:

PPR diagnostic system(s);
PPR surveillance system(s);
PPR prevention and control system(s);
Legal framework for prevention and control of PPR;
Stakeholders’ involvement on PPR control.

How to assess the evolution within a stage and from stage to stage?

The PPR Monitoring and Assessment Tool (PMAT) has been specifically designed to monitor and evaluate the implementation of the Strategy. To assess the performance of Veterinary Services to support the technical activities of PPR control and eradication, the OIE PVS Evaluation tool is also used.

Vaccination

Lessons learned from the Global Rinderpest Eradication Programme demonstrate that the use of a highly efficacious rinderpest vaccine capable of immunising animals against all rinderpest virus strains was a vital contributor to the campaign’s success. Similarly, efficient PPR vaccines are available and can induce life-long protective immunity in vaccinated animals.

Vaccination is thus one of the key tools to controlling PPR and has been identified as the main option in Stage 2 ‘Control’ and Stage 3 ‘Eradication’, of the Global Strategy for the control and eradication of PPR.

Implementing Public-Private Partnership (PPP) to upscale vaccination against PPR

In Kenya, PPP initiatives have been launched to support large-scale vaccination against PPR. Discover in this interview with Dr Obadiah Nyaga Njagi, OIE Delegate of Kenya, how these have benefitted to their national action plan.
