WHO guidelines for investigation of human cases of avian influenza A(H5N1)
The document reflects and incorporates the practical field experience gained by investigators working at international, national and sub-national levels during investigations of A(H5N1).Together with other key resources, the Guidelines can provide all levels of public health investigators with the essential information on how to conduct an investigation of human cases of A(H5N1). Using the Guidelines as a foundation, localities can develop operational plans and procedures tailored to their specific needs. The document will be updated as necessary to reflect increased understanding of A(H5N1) transmission and control and if the current pandemic threat situation changes. In addition to providing a national framework, the strategy defines the work of the food safety programme in the WHO Western Pacific Region for the next five years.
