See Influenza pandemic for government preparation for an H5N1 pandemic The social impact of H5N1 is the effect or influence of H5N1 in human society; especially the financial, political, social, and personal responses to both actual and predicted deaths in birds, humans, and other animals. Billions of dollars are being raised and spent to research H5N1 and prepare for a potential avian influenza pandemic. Over ten billion dollars have been lost and over two hundred million birds have been killed to try to contain H5N1. People have reacted by buying less chicken causing poultry sales and prices to fall. Many individuals have stockpiled supplies for a possible flu pandemic. Financial On November 1, 2005 US President George W. Bush unveiled the National Strategy To Safeguard Against The Danger of Pandemic Influenza backed by a request to Congress for $7.1 billion to begin implementing the plan. On January 18, 2006 donor nations pledged two billion US dollars to combat bird flu at the two-day International Pledging Conference on Avian and Human Influenza held in China. Over ten billion dollars have been spent and over two hundred million birds have been killed to try to contain H5N1. According to The New York Times, due to the H5N1 threat, as of March 2006: "governments worldwide have spent billions planning for a potential influenza pandemic: buying medicines, running disaster drills, [and] developing strategies for tighter border controls." Investment strategies are being altered to manage the effects of H5N1. This changes the valuations of trillions of dollars' worth of stocks worldwide as investors move assets in accordance with both fears and hopes. Poultry farming practices have changed due to H5N1: killing millions of poultry vaccinating poultry against bird flu vaccinating poultry workers against human flu limiting travel in areas where H5N1 is found increasing farm hygiene reducing contact between livestock and wild birds reducing open-air wet markets limiting workers contact with cock fighting reducing purchases of live fowl improving veterinary vaccine availability and cost. For example, after nearly two years of using mainly culling to control the virus, the Vietnam government in 2005 adopted a combination of mass poultry vaccination, disinfecting, culling, information campaigns and bans on live poultry in cities. The cost of poultry farming has increased, while the cost to consumers has gone down due to fears from H5N1 driving demand below supply, resulting in devastating losses for many poultry farmers.
