ABSTRACT

This report summarizes the results of a study undertaken in 2010 and 2011 to assess and map Influenza A (H5N1) virus transmission pathways in the poultry sector and critical control points along the poultry value chains in Egypt. In order to focus specifically on the factors that either increase the risk of spread of H5N1 HPAI disease or are critical in disease risk management, a risk pathways diagram is sketched to describe the pathways (transmission routes, carriers and mechanisms) for transmitting virus from an infected node throughout the poultry value chain to disease-free premises. To assess the risk, the probability of virus movement into and from each point along the risk pathway and the impact of disease transmission from an infected node to the next node along the value chain were assessed separately. Estimates of probability and impact were based on revision of quantitative epidemiological data and descriptive information from various sources, such as FAO study reports, General Organization for Veterinary Services (GOVS) reports and scientific literature. To fully understand all factors that contribute to the risk of virus transmission and to gather real-time information on control measures, activities, and priorities and information about historical outbreaks of HPAI...
