        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.
