Neighbors of Brazil including Argentina, Bolivia, Uruguay, Peru and Ecuador have all reported highly pathogenic strain H5N1 avian influenza in either or all  wild birds, backyard flocks or commercial farms. Peru reports the death of 700 sea lions and more than 65,000 wild birds. According to press reports, Brazil announced that suspect cases of HPAI in Rio Grande do Sul and Amazonas states were negative for the pathogen.

Producers in Brazil have implemented extreme biosecurity measures to prevent infection, although there is a probability that the disease might be introduced by migratory birds consistent with outbreaks in North and Central America, Asia and Africa
