Researchers cautiously eye new strain of swine flu: G4 EA H1N1

A new strain of swine flu with the potential to become pandemic has recently been identified by scientists in China. While it is not an immediate threat, the new virus has all of the signs of being highly adapted to infect humans, and should be closely monitored. If the virus mutates further, it could set off another global outbreak.
