Whooper swan migration is currently underway. There can be dozens or hundreds of swans together on migration routes and resting places, which facilitates the spread of the bird flu virus. There may be even more deaths of swans from bird flu during the autumn.

At the beginning of November, several whooper swans were delivered to the Finnish Food Authority, in which the highly pathogenic H5N1 type avian influenza virus was detected. The majority of the cases were found in Virolahti, where more than ten swans were found dead or sick near the eastern border in Kiiskijärvi. In addition, avian influenza has been detected in Oulu, and samples of swans found sick or dead are being examined, for example, in Haapajärvi and Puolanga.

No cases of illness have been reported in the South Karelia region, but the situation must be monitored.
There is no need to worry yet, but if you do come across dead waterfowl, it is important not to touch them with bare hands or otherwise handle them.
