“Avian Influenza is a critical challenge for the industry. Between 2013 and 2015, it caused the greatest losses in Canada and the USA (H5H7). In Mexico and Central America, there were outbreaks of H5N2 and H7N3; while in Chile, H7N3, H1N1 and H4 were present,” said Dr. Guillermo Zavala, Avian Health International, during his presentation at the Seminario Técnico para Maximizar la Efficienca de la Industria Avícola program at the 2016 International Production & Processing Expo. The program was presented entirely in Spanish.
In his presentation on Emerging Diseases in the American Continent (Enfermedades Emergentes en el Continente Americano), Zavala observed that avian influenza (AI) circulates mainly among wild birds in lake areas. It is also transmitted via insufficient biosecurity measures and infrastructure errors. Zavala remarked that vaccines do not eradicate AI, but help to prevent the virus, and preventive measures need to be accompanied by biosecurity.
Zavala also discussed other diseases, such as Erysipelas, Infectious Bronchitis, Infectious Laryngotracheitis and Mycoplasma, which are making an appearance again in commercial poultry. He remarked that they are less common thanks to increased biosecurity measures. However, they are still around.
