After Colombia went through most of 2024 with no cases of highly pathogenic avian influenza (HPAI), new detections have been confirmed in backyard non-poultry birds in the country.
The World Organisation for Animal Health (WOAH) reported that in Acandi, non-poultry birds in a backyard showing clinical signs characterized by unusual mortality.
The clinical signs observed included respiratory distress, cyanotic comb, loss of appetite, generalized weakness and, in some cases, death. Samples, including tracheal pool, cloacal pool and tissue samples, were taken to confirm the presence of the virus. Tests revealed that it is an H5 variant of HPAI.
According to WOAH, there were 100 birds that were susceptible, with 55 cases – 54 of which were fatal. The National Veterinary System is carrying out epidemiological tracing and follow-up activities in the area of origin of the affected birds. As a control measure, stamping out of the remaining 46 birds present in the affected premises is being carried out. In addition, epidemiological surveillance is being reinforced in the surrounding area to detect additional cases and prevent the spread of the outbreak.
According to WOAH, the last confirmed detection of HPAI in non-poultry birds in Colombia was in February 2024. That same month, it was announced that Colombia, Latin America’s fourth largest broiler and egg producer, would allow vaccination against HPAI and was working on a national vaccination plan.
The virus has so far never been confirmed in commercial poultry operations in the country.
