Abstract

This report includes a 2015 epizootic of highly pathogenic H7N3 avian influenza virus among captive and wild birds at "El Zapotal" ecologic reserve, located in the state of Chiapas, Mexico. Epidemiological control measures were implemented to prevent virus dissemination. The infection with the highly pathogenic H7N3 virus was detected predominantly among Plain Chachalaca (Ortalis vetula), with occasional detections in a White-fronted Parrot (Amazona albifrons) and a single Clay-colored Thrush (Turdus grayi). Here, we describe the characteristics of the outbreak environment, the surveillance strategy, the biosecurity measures, and the evaluation of the site, including external farms. These actions, timely implemented by the veterinary authorities, helped to contain the outbreak beyond the ecologic reserve. This contingency showed the importance of developing a more complete analysis of the existing risks and the challenges to implement minimal biosecurity measures in these facilities.
