The outbreak of highly pathogenic avian influenza H5N1 in Rio Grande do Sul has seen the number of dead birds rise to 15, with earlier reports confirming 9 deceased or sick swans. The affected birds, all wild, were located in the Taim Ecological Reserve, a protected area in the southern part of the state. The situation has been verified by the Department of Animal Health Surveillance and Defense of the State Government.

Avian influenza is a highly contagious viral disease primarily impacting birds, although it can also infect mammals and, in rare cases, humans who have direct contact with contaminated animals. The transmission occurs through secretions, feces, or infected carcasses, highlighting the potential health risks associated with this outbreak. In response to the increased mortality, the Taim Reserve has been closed indefinitely until the situation is brought under control.

Daily monitoring is being conducted in cooperation with official veterinary services to assess and manage the situation stringently. The local authorities are likely to continue their efforts to contain the outbreak and prevent further impacts on the wildlife population in the region, which could have broader implications for biodiversity and public health in the area, as well as concerns over the spread of the virus to domestic birds and livestock.
