Synopsis (short abstract) After H5N1 HPAI virus was reported in poultry in South East Asia in early 2004, it was only a matter of time before incursions were reported in Europe and countries of the Central Asia Region. It is widely believed that the virus was mainly spread through migration of wild birds, as well as cross-border trade. Whichever the explanation might be, it was quite evident that by mid 2005 this region was experiencing a major avian influenza H5N1 epidemic. Outbreaks were reported in the Russian Federat ion and Kazakhstan in July 2005, followed by Mongolia in August, Turkey in October, and Ukraine in November of that same year. The first outbreaks occurred in wild birds, followed by rapid spread to domestic poultry: both, backyard and commercial flocks. In January 2006, Turkey reported its first confirmed human case of avian influenza A (H5N1) infection and death, followed shortly thereafter by Azerbaijan in February. From 2006 to 2008, H5N1 HPAI has been repeatedly reported in Pakistan, Iran, Afghanistan and Turkey, which suggests that there are continuous reintroductions from an outside source.

    In late 2003 highly pathogenic avian influenza (A) subtype H5N1 (H5N1 HPAI) emerged in Southeast Asia causing poultry and economic losses on a large scale. Since 2004, the disease has spread to the rest of Asia, Europe and Africa. Despite the ongoing interventions on many fronts, including public education, surveillance sampling, restrictions on livestock movement, improvements in farm biosecurity, live-bird market disinfection, culling rounds, and vaccination campaigns, H5N1 HPAI continues to p ersist in China, Indonesia, Viet Nam, Bangladesh, and Egypt. Veterinary epidemiologists involved in influenza research recognize that this persistence suggests there are more complex epidemiological risk factors for the transmission and maintenance of this virus than originally identified...

    The recent number of H5N1 avian influenzarelated human cases in China's appears to lack the hallmark of nearby poultry outbreaks, writes CIDRAP News (21 January 2009), adding that this is a development that some public health officials worry could signal asymptomatic infections in birds. China has reported four human cases so far this year, three of them fatal...

    "Operational Research in Indonesia for More Effective Control of Avian Influenza" commenced in Indonesia in July 2008. Funded by USAID and the World Bank, the project aims to develop an evidence base for the selection of effective and feasible control alternatives in backyard poultry in Indonesia. These alternatives include mass voluntary vaccination against avian influenza (AI), and AI plus Newcastle disease and are implemented in the context of ongoing field Participatory Disease Surveillance and Response (PDSR) activities. The Food and Agriculture Organization (FAO) is supporting local government and the Ministry of Agriculture to implement the control strategies, and providing ongoing support for PDSR field activities. The FAO team works in close collaboration with JSI Deliver (responsible for procurement of vaccine, cold chain equipment and vaccination supplies, and providing logistical support for project implementation) and the International Livestock Research Institute (ILRI) ( responsible for the design of ORI HPAI, supervision of data collection and analysis of the research results).
