Query: The situation is being monitored by the World Health Organization but says "it is too early to know whether the virus is changing in ways that would signal the start of a human flu pandemic," says Maria Cheng a spokeswoman for the WHO. "It's one isolate from a single virus from Turkey.

If we started to see a lot more samples from Turkey with this mutation and saw the virus changing, we'd be more concerned."
