This brief has been extracted from the inception workshop proceedings held in Ethiopia, Ghana, Kenya, and Nigeria. In all of these countries, network maps (or Net-Maps) of information flows relating to avian influenza were prepared indicating the actors involved, their different kinds of linkages, and the influence that these actors have on making sure that the information about suspected outbreaks on the farm or market level reaches the national authorities and that an appropriate and timely response is implemented. The Net-Maps were based on experience with past interventions from the participants as well as their expert opinions. The Net-Maps also helped identify bottlenecks in communication and response that need further attention. This brief draws out the main findings from the Net-Maps of the study countries, including the potential breakpoints in the disease reporting and response networks.
