EPIDEMIOLOGY SOURCE OF EVENT OR ORIGIN OF INFECTION
The event is detected following surveillance and monitoring carried out by official staff. The affected farm is a commercial layer farm where unusual mortality was detected and intervention zones have been defined in the focal, perifocal and surveillance areas, accompanied by sampling of the farms and application of containment measures. Passive surveillance has been strengthened to detect new outbreaks. According to the monitoring carried out, a body of water near the farm where wild ducks arrive has been observed, and the H5N1 subtype was identified in this outbreak. According to the sanitary measures established for the control of highly pathogenic avian influenza (HPAI), in the sanitary control zones (perifocal zone), as part of the active surveillance established, a new outbreak was detected belonging to a laying hen farm, with epidemiological links to adjacent sheds, belonging to two owners, with a close epidemiological link. Control measures (killing and disposal) have been completed within this epidemiological unit. A new outbreak has been reported in the province of Cotopaxi, in a farm located in the perifocal zone, following a notification from the owner with a high mortality rate. In the province of Bolivar, two outbreaks were detected in backyard farms; one notification corresponds to a public health link (human-animal). There have been notifications that have been confirmed to avian influenza and correspond to laying hen and backyard farms in the province of Tungurahua and laying hens in Pichincha. There have been confirmed notifications of avian influenza in laying hens and backyard farms with ducks in the province of Cotopaxi and laying hens in Tungurahua. In the province of Cotopaxi, there is one confirmed notification of H5 influenza in ducks in an artificial water accumulation site in a military fort, whose purpose is recreational and which have occasional contact with wild ducks. There were confirmed notifications of H5 influenza in the new provinces of Azuay and Imbabura, respectively. There were confirmed notifications of H5 influenza in backyard poultry farms in the new provinces of Napo, Cañar and Morona Santiago, respectively. There was one confirmed notification of H5 influenza in backyard poultry farms in the province of Tungurahua. There were confirmed notifications of H5 influenza in the provinces of Cotopaxi in a commercial farm and Pichincha in a backyard farm. There was a new confirmed notification of H5 influenza in the province of Guayas. There was one confirmed notification of H5 influenza in the province of Tungurahua. Birds were purchased in the live bird market, where mortality was observed in the following days.
