A teenager remains in hospital with avian flu, according to British Columbia's top doctor. On Tuesday, Provincial Health Officer Dr. Bonnie Henry said the teen is suffering from severe respiratory distress. On Wednesday, the Public Health Agency of Canada (PHAC) confirmed it as avian flu — the first case of its kind in Canada. Henry said it's very likely that the B.C. teen's infection took place due to an exposure to either a sick animal or something in the environment.

As bird flu cases go underreported, health officials risk being slow to notice if the virus were to become more contagious. A large surge of infections outside of farmworker communities would trigger the government’s flu surveillance system, but by then it might be too late to contain.

In recent weeks, three human infections with the virus have been confirmed—all in dairy workers who had contact with sick cows. All three developed symptoms of eye infections known as conjunctivitis. The latest case, reported in Michigan this week, also involved respiratory symptoms more typical of a flu infection.

A third person in the US has tested positive for bird flu linked to an outbreak in dairy cattle, indicating possible cow-to-human transmission.

The FDA found pasteurized milk containing inactive bird flu virus remnants from infected dairy cows, but maintains the milk supply is safe.

When you see a wild bird such as a duck or seagull, think bird flu. Because it’s actually more likely than not they’re infected with the virus. And many species of wild birds are asymptomatic, meaning that they don’t show any symptoms.

Three cases of H3N8 detected in China since 2022 as WHO says strain doesn’t appear to spread easily between humans. First case resulting in death occurred in China.

Some of the world's leading makers of flu vaccines say they could make hundreds of millions of bird flu shots for humans within months if a new strain of avian influenza ever jumps across the species divide.

Cambodia has tested at least 12 people for the H5N1 strain of avian influenza, the health ministry said, after an 11-year-old girl died this week from the virus in the first known transmission to humans in the country in nearly a decade.
