        Epidemiological comments As a result of actions implemented to reinforce epidemiological surveillance in the State of Querétaro, two outbreaks of highly pathogenic avian influenza were identified, both backyard premises without clinical signs. Two other outbreaks were reported in backyard premises in the States of Tlaxcala and Guerrero and one outbreak in a commercial laying farm in the State of Querétaro. Surveillance is maintained in the zone around the affected farms without any evidence so far of sick or dead birds. The States of Querétaro, Tlaxcala and Guerrero have a low prevalence and vaccination against avian influenza virus H7N3 is applied, prior authorization from SENASICA. In the reported outbreaks of Mineral del Chico, Hidalgo; Colón, Querétaro (two outbreaks); Ezequiel Montes, Querétaro; Tlaxco, Tlaxcala and General Heliodoro Castillo, Guerrero, all the birds were killed and the carcasses, by-products and waste were officially disposed of, and the facilities were cleaned and disinfected. Likewise, IVPI results were obtained: 2.13, 2.53, 2.41, 2.43, 2.49 and 2.58, respectively.

              Epidemiological comments As a result of epidemiological surveillance, an outbreak was identified in a fattening farm in the municipality of Colón, State of Querétaro, in which the birds did not show clinical signs. In addition, two outbreaks in backyard premises, located in the states of Veracruz and Guanajuato, and another outbreak in a production of light breeders with clinical signs suggestive of highly pathogenic avian influenza (cyanosis, edema and swelling on the red comb and wattles and sudden death) were reported. In all four outbreaks, virus isolation was achieved and quarantine was implemented. The culling of all birds, and the disposal of carcasses, products and waste were completed in three of the outbreaks reported, while they are still underway for the outbreak in the municipality of Colón, Querétaro. IPIV titles were obtained for outbreaks in Santa Cruz de Juventino Rosas, Guanajuato (2.41); Coacoatzintla, Veracruz (2.25) and Colón, Querétaro (2.29). The States of Querétaro, Veracruz and Guanajuato have a sanitary condition with low prevalence and the vaccine against the H7N3 avian influenza virus is applied, following prior authorization from SENASICA.
