[TD]Following the notification by the owners of an increase in sudden death in birds at two backyards located in the States of Oaxaca and of Puebla, animals showing clinical signs suggestive of avian influenza were identified in both outbreaks. The official veterinary services launched the necessary epidemiological investigation and the presence of highly pathogenic avian influenza virus subtype H7N3 was confirmed. Control measures implemented immediately are, among others: quarantine, movement restrictions, stamping out and sampling in the focal and perifocal areas. Both outbreaks were confirmed as positive for avian influenza on 9 March and later by determining the intravenous pathogenicity index. So far, no epidemiological link has been identified between them.[/TD]
