"The purpose of this document is to provide brief guidelines on the sampling methods to use when conducting wildlife surveillance, or a morbidity / mortality investigation. Topics covered include animal handling, proper methods for collecting and transporting diagnostic samples related to investigation of avian diseases such as avian influenza, West Nile virus, and Newcastle disease."--Introd.

The highly pathogenic avian influenza H5N1 strain has spread from domestic poultry to a large number of species of free-ranging wild birds, including non-migratory birds and migratory birds that can travel thousands of kilometers each year. The regular contact and interaction between poultry and wild birds has increased the urgency of understanding wild bird diseases and the transmission mechanisms that exist between the poultry and wild bird sectors, with a particular emphasis on avian influenza. Monitoring techniques, surveillance, habitat use and migration patterns are all important aspects of wildlife and disease ecology that need to be better understood to gain insights into disease transmission between these sectors. This manual contains chapters on the basic ecology of avian influenza and wild birds, capture and marking techniques (ringing, color marking and satellite telemetry), disease sampling procedures, and field survey and monitoring procedures.--Publisher's description.

This publication contains a revised global strategy for dealing with H5N1 highly pathogenic avian influenza (HPAI) developed by the FAO and the World Organization for Animal Health (OIE), in collaboration with WHO, and drawing on experiences and lessons learned since the panzootic started in late 2003. This third revision sets out a long-term vision and goals, identifies priorities and strategic approaches, and proposes actions at national, regional and global levels to control and ultimately eradicate the disease.

Until today, more than 100 years after its first description in Italy, the highly pathogenic avian influenza virus (HPAIV) has not lost its fearsome character for wild birds, poultry and humans. On the contrary, the number of outbreaks with high casualty rates in wild birds and poultry has multiplied in recent years and cases of zoonotic infections are also increasingly reported from HPAI endemic areas. The epidemiology of these infections is complex and also involves surface water and possibly sediments of shallow standing waters, which could play a role as a vector medium and/or virus reservoir. The goal of this project was to expand current knowledge of the influence of water on the spread of AIV. As part of this project, we were able to ... 1. ...improve AIV detection methods using real time RT-PCR in terms of sensitivity and breadth of viruses detected. In addition, we succeeded in economizing the procedure so that fewer resources are required and results are obtained faster (publication I: [173]). 2. ...develop an ultrafiltration-based enrichment method for AIV from surface water and evaluate it with field samples from HPAI outbreak areas in wild bird habitats (Wadden Sea coast of Schleswig-Holstein) and previously unaffected regions (Antarctic Weddell Sea) (publication II: [174]). Furthermore, protocols for testing different environmental sample matrices for AIV screening were tested and compared to results of passive monitoring by dabbing diseased or dead wild birds ...

Over the past 20 years, highly pathogenic avian influenza (HPAI), specifically Eurasian H5N1 subtypes, caused economic losses to the poultry industry and sparked fears of a human influenza pandemic. Avian influenza virus (AIV) is widespread in wild bird populations in the low-pathogenicity form (LPAI), and wild birds are thought to be the reservoir for AIV. To date, however, nearly all predictive models of AIV focus on domestic poultry and HPAI H5N1 at a small country or regional scale. Clearly, there is a need and an opportunity to explore AIV in wild birds using data-mining and machine-learning techniques. I developed predictive models using the Random Forests algorithm to describe the ecological niche of avian influenza in wild birds. In "Chapter 2 - Predictive risk modeling of avian influenza around the Pacific Rim", I demonstrated that it was possible to separate an AIV-positivity signal from general surveillance effort. Cold winters, high temperature seasonality, and a long distance from coast were important predictors. In "Chapter 3 - A global model of avian influenza prediction in wild birds: the importance of northern regions", northern regions remained areas of high predicted occurrence even when using a global dataset of AIV. In surveillance data, the percentage of AIV-positive samples is typically very low, which can hamper machine-learning. For "Chapter 4 - Modeling avian influenza with Random Forests: under-sampling and model selection for unbalanced prevalence in surveillance data" I wrote custom code in R statistical programming language to evaluate a balancing algorithm, a model selection algorithm, and an under-sampling method for their effects on model accuracy. Repeated random sub-sampling was found to be the most reliable way to improved unbalanced datasets. In these models cold regions consistently bore the highest relative predicted occurrence scores for AIV-positivity and describe a niche for LPAI that is distinct from the niche for HPAI in domestic poultry. These studies represent a novel, initial attempt at constructing models for LPAI in wild birds and demonstrated high predictive power.
