OIE analyses avian influenza control methods around the world

Paris, 14 February 2012 – Two exhaustive OIE analyses of global avian influenza control published in the December issue of the OIE Scientific and Technical Review (30(3), 2011) conclude that stamping-out of infected and in-contact animals is the preferred method of avian influenza control in the majority of situations and that efficacy of control is rooted in well-performing Veterinary Services.

However, in the first study OIE experts show that the use of vaccination is “suitable when stamping-out programmes are unsuccessful or if Veterinary Services are not adequate, and diagnostics and surveillance not effective…”.

The study reviewed chosen options and efficacy of control measures in 80 OIE Member Countries where outbreaks of highly pathogenic (HPAI) and low pathogenic avian influenza (LPAI) occurred in both poultry and/or wild birds between 2002 and 2010.

Efficacy of control rooted in capacity of Veterinary Services

The second research shows that countries with effective and efficient Veterinary Services (according to independent evaluations led by using the OIE Tool for the Evaluation of Performance of Veterinary Services) demonstrate better HPAI control measures than in other countries.

It also shows that high poultry density correlates with more and longer outbreaks of HPAI, which influences the time it takes to eradicate the disease in affected countries.

The research draws data on OIE Member Countries’ situation regarding avian influenza for the period 2002-2010 from OIE’s Handistatus II and the World Animal Health Information Database (WAHID), which it correlates with economic indicators of surveyed countries.
