First evidence of peste des petits ruminants (PPR) virus circulation in Algeria (Sahrawi Territories): outbreak investigation and virus lineage identification
Following reports of increased mortality in the small ruminant population of the Sahrawi territories, western Algeria, between January and May 2010, local veterinary authorities suspected an outbreak of peste des petits ruminants (PPR). An investigation was implemented in May 2010 and followed up in October 2010 in the Sahrawi refugee camps, Tindouf province, with the objective of confirming the circulation of the peste des petits ruminants virus (PPRV). Laboratory results confirmed the presence of PPRV in 33.3% of the samples. Sequence analysis revealed that the virus belonged to Lineage IV and phylogenetic analysis indicated a close relationship (99.3%) with the PPRV isolated during the Moroccan outbreak in 2008.
