H5N1 strikes Vietnam again as European H5N8 detections continue

In the latest avian flu developments, Vietnam reported another highly pathogenic H5N1 outbreak and Denmark and Finland reported more H5N8 detections. Also, Taiwan reported several more outbreaks caused by low-pathogenic H5N2, according to the latest notifications from the World Organization for Animal Health (OIE).

Vietnam, which has been battling a steady stream of H5N1 and H5N6 events, reported a new H5N1 outbreak in backyard poultry in Quang Ninh province in the north. It began on Apr 27, killing 2,000 of 5,000 susceptible birds.

In Europe, Denmark reported 11 H5N8 detections, all in wild birds found dead from Jan 2 to Apr 4 across a wide part of the country, many of them forested areas. The virus was confirmed in 14 birds, many of them birds of prey. And Finland reported that tests on a white-tailed eagle found dead on Apr 8 near the Aland Islands in the far southwest were positive for H5N8.

Elsewhere, Taiwan reported six more outbreaks linked to low-pathogenic H5N2, but they were all from 2015, but pathogenicity results were just confirmed on Apr 18. The island is still battling low-pathogenic H5N2 alongside highly pathogenic H5N2, H5N3, H5N6, and H5N8. According to the OIE report, abnormal deaths were observed on five poultry farms, and symptoms were also seen in poultry carcasses at a slaughterhouse in Taipei City. The events led to the slaughter of 91,485 birds.
