The Ministry of Livestock, Agriculture, and Fisheries (MGAP) also confirmed it was the first case of the malady in a wild mammal. Several birds had been arriving at the Uruguayan shores with symptoms that suggested avian influenza, which hit other parts of the world and which, in the last few weeks, caused hundreds of deaths on the Atlantic coast of Argentina.​..

They located 400 dead sea lions or sea lions due to avian flu
The infections seem to spread among this species of mammals.
by Editorial
September 29, 2023

The number of lions and sea lions killed by bird flu continues to rise. A latest report from the National Directorate of Aquatic Resources (Dinara) of the Ministry of Livestock, Agriculture and Fisheries (MGAP) indicates that 400 dead lions and sea lions have already been detected with H5N1 flu. The so-called avian flu mutated and in the region of birds it passed to mammals, in this case wolves and sea lions. This is due to having contact especially with infected seagulls.

In Argentina, 950 sea lion deaths have been recorded in the Mar del Plata area. In Chile, mutations were found in the virus isolated from sea lions that could indicate some degree of adaptation. This was also observed in minks in Spain.

In Uruguay, the director of Dinara, Jaime Coronel, said that “it is a situation that is gradually increasing. “We are having an increase in deaths.” In statements to Subrayado (channel 10) he indicated that more than half of the deaths occurred in and followed by Maldonado and Canelones. Further towards the Río de la Plata mortality decreases with some cases in Montevideo and one in San José and another in Colonia.

Coronel stated that “the discovery of dead animals or animals with symptoms on the coast may not correspond to the time of the disease and mortality, because there may be specimens that die in the water and the current means that they do not reach the shore for a few minutes.” days".

He reiterated that people and pets should be kept away from amrine wolves that are either resting, dying or dead and Dinara should be notified.

Although contagion to people has not been confirmed, if someone touches any of these animals and during the next ten days develops fever, cough, sore throat, runny nose, headache and/or shortness of breath, they should consult a doctor. doctor .​
