Overview
- SENASA confirmed a highly pathogenic H5 outbreak at a commercial egg farm in Alejo Ledesma, Córdoba, the first in that province and the third affecting a commercial site nationally.
- Containment measures at the Córdoba facility include interdicting the farm, establishing a 10‑km sanitary control zone, culling, and supervised cleaning and disinfection.
- Earlier detections were confirmed in wild birds in General Madariaga and in domestic poultry in Ranchos and Lobos (Buenos Aires province), as well as in coscoroba swans at the Costanera Sur reserve in Buenos Aires city.
- The Health Ministry’s epidemiological alert instructs teams to notify SNVS 2.0, monitor exposed people for 10 days, collect diagnostic samples within four days of symptom onset, and consider oseltamivir based on clinical evaluation.
- Authorities say no human cases have been confirmed, a recently suspected case tested negative, transmission to people is uncommon and not sustained between humans, and consumption of poultry or eggs does not spread the virus; the export sector faces restrictions after loss of disease‑free status, with China closed but about 47% of destinations still open under zoning rules.
