The H1N1 influenza virus from swine had a large and unexpected effect in 2009 when he started to infect the human. Arose from rearrangements suffered since 1930, and found viral segments characteristic of human, bird and two different types of pigs. The biggest problem of the influenza virus is zoonotic power, that with these rearrangements and transmission between species, may at any time culminate in a catastrophic pandemic, for example, the H1N1 from 1918 to 1919, where researchers has proposed initially direct transmission from birds to humans, although during this time, the disease has also been reported in the pig population, and it is unclear whether the virus was transmitted from animals to humans or humans to animals.The Brazilian poultry industry is currently a very successful activity. The use of environmental planning associated with new technologies is reflected in the extraordinary growth in activity. The Brazilian production of chicken surpassed the annual 10 million tonnes in 2007. Brazil is among the three largest poultry producers in the world ranking, along with the United States and China.The importance of poultry production for the country, the generation of social and economic benefits, the risk that the entry of avian Influenza is for the Brazilian poultry industry is huge. An outbreak of this disease in a center of poultry production would represent a risk to the economy and would affect negatively the levels of protein intake of quality and affordable to the population. In order to establish a monitoring of the virus of Avian Influenza in migratory birds will be collected samples of cloacal swabs for oral and analyzed by Real Time PCR (qPCR), and blood serum tests, with the larger goals, contribute to strengthening of animal health protection services, increase research capacity, and finally, update and harmonize standards and procedures for the prevention and control of Avian Influenza, referring to the recommendations of the World Organization for Animal Health (OIE) and World Health Organization (WHO).
