JUST IN: CDC announces first severe case of Bird Flu showing mutations, prompting "experts" to warn that we may see another pandemic.

"The virus may mutate and become more easily transmitted person to person," said infectious disease expert Dr. Dean Blumberg.

"The more this virus circulates and specifically co-circulates with human strains, that's going to increase the odds of the virus evolving to more human-to-human transmission and that that of course, could signal another pandemic."
