More than 30 partner institutions attended the fifth regional meeting of the Asian Partnership on Emerging Infectious Diseases (APEIR) at Kunming in China. The researchers discussed the outcomes of the five projects and presented key findings to the media on 15 January.
This study concluded that wild birds are likely transmission vectors of avian influenza (AI), H5N1. There are differences between countries and between bird species. Wetlands and lakes along the flight paths of migratory birds are zones where highly pathogenic avian viruses remain viable and can be spread through wild bird migration. The study shows that some migratory birds' flight paths are closely related with outbreaks of H5N1 in poultry in space and time. The work has led to new H5N1 detection mechanisms and raised research priority on the role of wild birds in transmission of AI.
The research has raised further questions on transmission of H5N1 and other viruses among birds and poultry.
AI outbreaks and measures taken to control highly pathogenic avian influenza (HPAI) have a significant impact on production and income of small-scale commercial producers, but less impact than expected on farmers who keep a few backyard poultry. The team found three main factors could reduce the socio-economic impact, namely: selected rather than mass culling, increased compensation rates for culled birds, and the targeting of sector support policies towards small-scale commercial producers.
Based on interviews with farmers, traders and communities at large, the research improved awareness of AI risks and encouraged community-driven actions to reduce transmission of AI and other poultry disease. The researchers concluded that changing individual farmers behaviour is difficult and organisational reform at the village level is a more successful approach. In the future the group would like to work to map poultry movement both within and between countries.
The team set out to understand the generation of policy for stockpiling retroviral drugs for humans and vaccination for poultry. Across the region the first priority is for human health and all countries are stockpiling retroviral drugs as per WHO guidelines, but coverage is constrained by finances. Poultry vaccination policies differ between countries because of economic drivers for poultry industry.
Different inter-sectoral strategic interests result in incoherent regional and possibly global health strategies. The team hopes their research will lead to strategies that take into consideration differences in national needs.
The objective is to evaluate factors contributing to success in prevention and control of AI in the poultry sector and the team set out to describe and analyse prevention and control strategies and evaluate their effectiveness. The measures prescribed are not always implemented as well as authorities may believe and as such may not be having the effect they should. The work will provide a valuable reference in policy making against AI and future pandemics.
