premise: A new strain of Avian Flu or Bird Flu has been discovered in China and has also infected some humans. The virus also "spreads fast" and has covered a "big geographic region" according to Chinese health officials. It is not known how dangerous the new virus is and whether it is stronger or deadlier than the current H5N1 virus. Despite being detected in humans, no evidence has turned up to suggest that the virus can be spread easily from human to human.
hypothesis: 483Lu suffers from the H5N1 virus.
