Bid to end PPR

Irish Examiner - Farming - - COVER STORY -

Re­searchers have found that re­peated vac­ci­na­tion cam­paigns tar­get­ing vi­ral reser­voirs may be the most ef­fec­tive way of erad­i­cat­ing Peste des Petits Ru­mi­nants (PPR), an an­i­mal dis­ease tar­geted for global erad­i­ca­tion.

The breakthrough comes as thou­sands of sheep and goat are eu­thanised in east­ern Bul­garia as part of an erad­i­ca­tion strat­egy.

The Food and Agri­cul­ture Or­gan­i­sa­tion of the United Na­tions, and the World Or­gan­i­sa­tion for An­i­mal Health have launched global ef­forts to erad­i­cate PPR, also known as ovine rinder­pest. So far, only two in­fec­tious dis­eases have ever been erad­i­cated, small­pox in hu­mans and rinder­pest in cat­tle. The FAO and WOAH’s mass vac­ci­na­tion strat­egy is costly and lo­gis­ti­cally chal­leng­ing, due in par­tic­u­lar to the mo­bil­ity and the lack of ac­ces­si­bil­ity of small ru­mi­nant flocks, and the lack of ac­cu­rate herd data. That’s why “Iden­ti­fy­ing high­risk pop­u­la­tions and tai­lor­ing vac­ci­na­tion strate­gies to lo­cal epi­demi­o­log­i­cal con­texts is es­sen­tial,” said Dr Guil­laume Fournié, Se­nior Re­search Fel­low at the Royal Vet­eri­nary Col­lege.
