13 Signs You've Caught Swine Flu

It has pandemic potential.

As cases of coronavirus mounted across the United States, officials announced this week that another flu outbreak might be on the horizon: A variant of swine flu has emerged in animals in Asia and "has pandemic potential," researchers say. While this latest variant hasn't yet infected humans, swine flu is nothing new to health officials. H1N1 caused a pandemic in 2009, infecting more than 1 million people in the U.S. These are the common signs of swine flu.
