Argentina, Uruguay confirm first cases of influenza in wild birds

Argentina and Uruguay confirmed on Wednesday the first cases of highly pathogenic avian influenza in their territories. In both cases, the disease was verified in wild birds, which have been found dead in national parks in recent days. The Brazilian government is already in contact with the authorities in neighboring countries to understand the risk of the virus crossing the border.On Monday, five black-necked swans appeared dead off the coast of Laguna Garzón, Uruguay, with symptoms of the disease. Laboratory tests confirmed the health authorities’ suspicions. In Argentina, Andean geese found in Laguna de los Pozuelos, in the north of Jujuy province, tested positive for the disease."It’s not a surprise," officials from both countries said during press conferences to detail the cases and talk about measures. "Analysis of epidemiological evolution showed the dreaded disease present in all continents and advancing in North and South America," said Fernando Mattos, Uruguay’s minister of Agriculture.Avian flu is a highly contagious disease that affects domestic and wild birds and can cause great losses to farmers. Mr. Mattos explained that because these are cases in wild animals, there will be no embargo on protein exports."We are taking the necessary measures to preserve poultry production, which is an important activity," he said. "It’s a major threat to backyard poultry, which usually don’t have the same biosecurity levels as commercial farms."Mr. Mattos stressed that the chances of the disease being transmitted to humans are low. The two cases recorded to date - in 2022 in the United States and 2023 in Ecuador - were due to very close contact between sick birds and humans. "The disease is not transmitted to humans by consuming the meat," he said.In a press conference, Brazil’s Agriculture Minister Carlos Fávaro said that the country will strengthen active surveillance of avian influenza after the confirmation of new cases in South America. The place where an infected bird was identified in Uruguay is only 180 kilometers from the border with Rio Grande do Sul.He said that there will be no interruption in the flow at the borders, but that surveillance will be intensified. As there is no importation of products from neighboring countries where cases have already been...
