A Canadian teenager is in critical condition after contracting H5N1 bird flu, caused by a genotype found in wild birds, not dairy cattle as in the U.S. Genetic sequencing confirms the virus, but the source of the infection remains unknown. The teenager had no known exposure to infected poultry but had contact with pets. This is the first confirmed H5N1 case in Canada, raising concerns due to the virus’s history of severe illness. Health officials are monitoring close contacts for symptoms and conducting blood tests for antibodies. The possibility of further cases remains uncertain, but experts remain vigilant.
