H5N1 Confirmed in Gull at Playa Bagdad as Tamaulipas Imposes Sanitary Cordon

Health teams begin a 14-day active search for exposures after months of seabird deaths with no human infections confirmed.

Overview

  • SENASICA confirmed H5N1 after a gull collected by CONIBIO Global in early September was submitted for testing, prompting an epidemiological alert.
  • Authorities report roughly 400 dead seabirds at the Playa Bagdad nesting islets since March, with carcass collection and safe burial underway.
  • Six volunteers who handled remains are under medical observation, one is isolated with fever and headache, and laboratory results are pending.
  • A sanitary cordon has been established, house‑to‑house surveillance is ongoing near the beach, and residents are urged to avoid the area.
  • SENASICA sources cited by Excélsior say Playa Bagdad is currently the country’s only active focus, as migration season raises monitoring concerns.
