HPAI continued to expand in the Americas and is expected to reach the Antarctic in the near future. Infections were detected in six new mammal species for the first time, including marine mammals and mustelids. Two cases were reported in cats in the USA and one case in a dog in Canada. As a precautionary measure, EFSA recommends preventing pets from being exposed to dead or diseased animals in areas affected by HPAI.

The risk to the general public in Europe remains low, and low to moderate for workers and other people in contact with potentially infected diseased and dead birds and mammals.
