Why has bird flu killed millions of wild and domestic birds, touched seals and sea lions, mink farms, cats, dogs and others but hardly touched people? That's "a little bit of a head-scratcher,” although there are some likely explanations, said Richard Webby, a flu researcher at St. Jude Children’s Research Hospital in the US state of Tennessee. It could have to do with how infection occurs or because species have differences in the microscopic docking points that flu viruses need to take root and multiply in cells, experts say. But what keeps scientists awake at night is whether that situation...

The most recent case was the first to have typical influenza symptoms, auth...

Officials added that they're continuing to study the issue. “To date, we have seen nothing that would change our assessment that the commercial milk supply is safe,” the FDA said in a statement.

While uncommon in humans, when a person is infected, the mortality rate is about 60 per cent, according to the World Health Organization (WHO). The Texas patient’s only symptom was eye inflammation or redness, according to the US Centers for Disease Control and Prevention (CDC), which confirmed th...
