Update avian influenza

Since October 2020 The DWHC and Sovon have collected more than 400 dead wild birds to be tested for avian influenza virus at WBVR in Lelystad, The Netherlands.  Most of the collected birds were individuals, because the NVWA deal with the reports of 3 or more dead waterbirds.

In table below are the bird species listed that were collected by the DWHC and Sovon and  were tested positive for (highly pathogenic) avian influenza. Of course this is not a complete list ofbirds that can be infected with (highly pathogenic) avian influenza.
