Last year, 17 countries, 【C2】______ from Germany to Japan, reported outbreaks of H5N1 in 【C3】______ poultry and wild birds; and the World Health Organization, which still says H5N1 causes a worldwide threat, recoded 72 human 【C4】______ , 32 of them fatal.

Others reported that reducing risk among those 【C12】______ backyard poultry has to be a community-wide effort, since changing the practices of 【C13】______ farmers has proven difficult.

He also adds that there is a high 【C17】______ of outbreaks in poultry and passerine movements.
Wiriyarat says it is still 【C18】______ what is causing the outbreak, whether there is a natural storage for H5N1, and how the virus is 【C19】______ between domestic and wild birds.
