The Pan American Health Organization has reported outbreaks of avian influenza in 16 countries in the Americas, including Canada, United States, Mexico, and several countries in Central and South America. Brazil, a major poultry producer, has not yet reported any cases but is implementing a disease contingency plan and preparing preventive measures to protect its poultry industry. The risk period for the disease is between April and May due to migratory birds.
