Abstract

This study was carried out to assess the impact of swine eradication strategy on the occurrence of Avian Influenza H5N1 in poultry backyards, poultry farms and human population, to identify risk factors for H5N1 around swine colonies in Egypt. The studied regions included three Governorates (Giza, Cairo and Qalyoubya).
A total of 73 poultry backyard, 95 poultry farms and 168 human samples were examined for the presence of H5N1 before the eradication of swine. Moreover, a total of 67 poultry backyard, 85 poultry farms and 152 human samples were examined for the presence of H5N1 after the eradication of swine. All samples were examined by using real time PCR.
The results revealed that 16 poultry backyards were positive before the eradication of swine while, 5 backyards were positive after applying this strategy. Also, 6 poultry farms were positive before applying the strategy and 3 farms were positive after the eradication of swine. In suspected humans; 22 and 9 cases were confirmed for the presence of H5N1 before and after the eradication of swine respectively.
 In conclusion, the applied swine eradication strategy had a significant impact on the control of H5N1 in backyard poultry, and human population. Conversely, there is no significant impact of the swine eradication on farm poultry.
