Teen sickened with Canada's first human case of bird flu is in critical condition and the source remains a mystery

A teenager in Canada is critically ill with the first human case of H5N1 bird flu contracted in the country, and public health officials aren't sure how the youth was exposed.
The teen had no known exposure to livestock such as cattle or poultry, where the virus is known to be circulating. The strain that sickened the teen, however, is different from the version that is infecting cows and has spread to dozens of dairy workers in the U.S.
Instead, the variant in question, a 2.3.4.4b virus of the D1.1 genotype, typically circulates in wild birds and poultry, according to StatNews.
...................
Since 2022, the virus has been popping up in mammals, causing devastating outbreaks in sea lions and elephant seals and spreading in dairy farms. At least 46 people in the U.S. have contracted the virus in 2024, according to the Centers for Disease Control and Prevention (CDC).
These illnesses have been mild so far, but H5N1 can cause severe disease; more than half of cases detected worldwide since 2003 were fatal, according to the WHO. This statistic does not account for mild, undetected cases that were likely circulating in this time, but does suggest a concerning mortality rate for H5N1 should it become better at spreading between people...................

The Wash Post has a story on this also but I do not have a subscription to it.

Seasonal flu vaccines do not provide protection against avian influenza A viruses. CDC has developed H5 candidate vaccine viruses (CVVs) that are nearly identical or, in many cases, identical to the hemagglutinin (HA) protein of recently detected clade 2.3.4.4b avian influenza A(H5N1) viruses in humans, birds and other mammals. These H5 CVVs could be used to produce a vaccine for people, if needed, and preliminary analysis show that they are expected to provide good protection against avian influenza A(H5N1) viruses currently circulating in birds and other animals. More information about Making a candidate Vaccine Virus (CVV) for a Highly Pathogenic Avian Influenza A Virus is available.
Let's hope the trump admin doesn't shut this down.
