The world risks a repeat of the disastrous 2006 bird flu outbreaks unless surveillance and control of this and other dangerous animal diseases is strengthened globally, FAO warns.
"The continuing international economic downturn means less money is available for prevention of H5N1 bird flu and other threats of animal origin. This is not only true for international organizations but also countries themselves," says FAO Chief Veterinary Officer Juan Lubroth.
Continued strict vigilance is required, however, given that large reservoirs of the H5N1 virus still exist in some countries in Asia and the Middle East, in which the disease has become endemic. Without adequate controls, it could easily spread globally as it did at its peak in 2006, when 63 countries were affected. Investing more in prevention makes economic sense given the huge toll inflicted by a full-scale pandemic. Between 2003 and 2011 the disease killed or forced the culling of more than 400 million domestic chickens and ducks and caused an estimated $20 billion of economic damage.
Appropriate measures can completely eliminate H5N1 from the poultry sector and thus protect human health and welfare. Domestic poultry are now virus-free in most of the 63 countries infected in 2006, including Turkey, Hong Kong, Thailand and Nigeria. And, after many years of hard work and international financial commitment, substantial headway is finally being made against bird flu in Indonesia.
Investing in prevention means improving hygiene practices, market and border controls, and health security in farms and markets. It includes equipping laboratories and training staff to diagnose and respond to disease outbreaks, and in organizing efficient extension services to serve farmers' needs.
Despite tight budgets, international organizations should also try to do more through concerted action.
