The dead gulls were found on April 30 in the vicinity of Kraggenburg, just across the provincial border of Overijssel with Flevoland. Omroep Flevoland spoke to researcher Jelle Boontje of DWHC, who concluded that this variant of bird flu is so contagious that all gulls found have succumbed to it. According to the researcher, the virus continues to emerge, also this week.
