As of May 2026, Chile is grappling with a significant resurgence of Highly Pathogenic Avian Influenza (HPAI). This latest wave is characterized by an extensive geographic spread toward the southern regions of the country and, notably, the first incursions into commercial production facilities in recent times.
According to data from the Chilean Ministry of Agriculture and the World Organisation for Animal Health (WOAH), the current epidemiological situation reflects a sharp escalation in viral prevalence:
- Active Outbreaks: Approximately 50 active outbreaks have been identified nationwide to date.
- Distribution: The disease has been detected in 25 backyard holdings, 22 wild bird locations, and 3 commercial poultry farms.
- Impact: To date, more than 700,000 birds have either died from the virus or been culled as part of eradication measures.
Current epidemiological trends indicate that migratory waterfowl, most notably the Black-necked swan, continue to serve as the primary vector for the transmission and spread of the disease across the Chilean territory.
