Canadian Teen Hospitalized with Bird Flu Raises Concerns Over H5N1 Spread

A teenager in British Columbia is in critical condition with a presumptive H5N1 bird flu infection, raising concerns about the virus's unknown transmission routes. This case is significant, as it is the first reported in Canada amidst a wider outbreak affecting millions of birds and some mammals in North America. Health officials are investigating the source of the infection, noting that the teen had no direct interaction with infected birds. Experts warn that as avian flu spreads across livestock, human cases could increase, necessitating stronger surveillance and preventive measures.
