Résumé : Highly pathogenic avian influenza (HPAI) H5N1 virus was first reported in Africa in February 2006 in Nigeria and subsequently infected ten other countries producing considerable socioeconomic losses. The epidemiological characteristics of HPAI H5N1 outbreaks seem to differ from those observed in Asia and this unexpected behaviour has hindered efforts for surveillance and control of the disease. The aim of this study is to improve the understanding of the epidemiology of HPAI in Africa by assessing risk factors for introduction, spread and persistence of HPAI outbreaks in seven infected countries (Burkina Faso, Cameroon, Egypt, Ivory Coast, Niger, Nigeria and Sudan). Standardised methods will be used to review existing HPAI-related information, conduct retrospective HPAI outbreak investigations with biological sample collection, compare infected and non-infected areas, and collect risk factor information at the national level. Collected data and samples will be analysed to provide a standardized description of HPAI situation and outbreak patterns in the seven infected African countries included in the survey, to assess risk factors related to introduction, spread and persistence of HPAI, and to predict, to the best of the available knowledge, areas with the highest likelihood of occurrence of HPAI. Activities will be conducted by a team of national experts (one national survey consultant specifically recruited for the survey in each participating country, agents of the national veterinary services and national veterinary diagnostic laboratories) and international experts from CIRAD, FAO, FLI, IZS, RVC and ULB. The final outcome will be the writing of recommendations to enhance the efficiency of HPAI prevention and control strategies in Africa.
