Epidemiological comments The National Health, Safety and Food Quality Service (SENASICA) has lifted the sanitary alert after more than 90 days without new cases of highly pathogenic avian influenza H7N3 in the affected areas. The total definitive quarantine that prevented birds from entering and leaving the affected farms was also lifted. Passive epidemiological surveillance, which consists of paying immediate attention to clinical suspicions of the disease, is maintained permanently, particularly those associated with high mortality in poultry and other susceptible birds. In view of the above and the fact that the three-month period has elapsed without any evidence of the circulation of the virus in question, in accordance with the provisions of Article 10.4.3 of the Terrestrial Animal Health Code, this sanitary event is considered closed.
