and human-to-human virus transmission leaves areas for further work. These results support previous fi ndings that knowledge about avian infl uenza, especially about prevention and human-to-human transmission, has scope for improvement (4,5). Persons in Europe reported that they have little ability to prevent themselves from getting avian infl uenza (6). Previous research in the Lao People’s Democratic Republic examined how consumers’ knowledge of avian infl uenza risk reduced the likelihood that consumers will substitute poultry for other foods during an avian infl uenza crisis. This research indicates the importance of informing persons about consumption and transmission-related risks to reduce the likelihood of unnecessary behavioral changes that can cause larger macrolevel market effects (7). The state of knowledge about avian infl uenza in Europe during the outbreak in the spring of 2006 leaves room for further public health information campaign efforts, especially those that increase consumers’ understanding of consumption-related avian infl uenza risks. Persons in Europe appear to be aware of culling procedures and the risks of touching infected birds but have a more limited understanding of how avian infl uenza in their region should infl uence their consumption patterns.
