    • Epidemiological comments
      • During the epidemiological surveillance carried out in response to the event, the National Food Quality, Food Safety and Health Service (SENASICA) has taken samples in the outbreaks and around the outbreaks in 148 poultry farms.
      • 31 farms were identified by viral isolation, diagnosis is ongoing in other 83 and 34 have tested negative to H7N3 highly pathogenic virus.
      • The population at risk in these 148 farms amounts to about 17 million birds, of which 86.1% of layers, 6.9% of broilers and 7% of breeders.
      • As part of the measures taken to reduce the risk, the buffer zone has been extended to 60 km around the index outbreak and includes 161 poultry farms at risk with a population of 25.8 million of birds.
      • Control measures on birds and their products movements have been strengthened in the quarantine area and eight check points have been established with the support of 26 health technicians with 9 vehicles that monitor the quarantine zone.
      • Epidemiological surveillance activities continue in the outbreaks, around the outbreaks and in the buffer zone.
      • As a measure to reduce the risk, sampling will be carried out in neighbouring States and in poultry farms at risk outside the buffer zone.
    • Control measures
      • Measures applied
        • Stamping out
