According to the agency, an active outbreak persists at the Carlos Anwandter Nature Sanctuary, where 229 birds died between April and June, including 228 black-necked swans.

  The report adds that 100 percent of the specimens analyzed in this group tested positive for avian influenza.

  However, a survey of domestic poultry farms located within a one-kilometer radius of the sanctuary did not find any domestic birds with symptoms consistent with the disease.

  The National Service to Prevent and Mitigate Disasters (Senapred), the Agricultural and Livestock Service (SAG), and municipalities in the region urged the public to immediately report any birds exhibiting symptoms of avian influenza, or any dead birds, to prevent the spread of the virus.

  The official SAG website pointes out that since the beginning of the outbreak, 44 events have been detected in nine of the country’s 16 regions, and 888,468 birds have died or been culled, the majority (883,503) in industrial facilities.
