The ace wild birds, mainly migratoryare the natural host of the virus and are the main factor in its spread throughout the Americas. Poultry populations can contract the disease through contact with infected wild birds. In birds, the avian influenza virus is excreted in faeces and respiratory secretions and can be transmitted by direct contact with the secretions of infected birds or indirectly through contaminated water.

So far the Transmission from animals to humans is very rare. In America, since last year, only 2 cases of people affected by bird flu have been reported, who had been in close contact with birds. One case was reported in the United States on April 29, 2022. The second case was detected in a girl in Ecuador on January 9. Although the risk of transmission is considered low, those considered at risk are those who have had direct contact without adequate protection with infected animals (alive or dead) or with their contaminated environment. Plucking, handling infected poultry carcasses and preparing poultry for consumption, particularly in a domestic setting, may also be risk factors.

The detection of the first case of AI in a farm in the Río Negro commercial circuit led to the loss of disease-free status for Argentina and self-suspension of exports of poultry products.
