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.
Every week, the NVWA* creates a new map with the locations of dead wild birds that tested positive for the highly pathogenic avian influenza (bird flu) H5N8.
