Is a dangerous bird flu on the horizon? - UPI.com
UPI reports: "Scientists have found new evidence that the H7N9 bird flu, currently confined to China, has the potential for a widespread outbreak. Public health experts have long been tracking the bird flu strain, which emerged in humans in 2013. Since then, nearly 1,600 cases have been confirmed in China -- with a death rate of about 40 percent, according to the U.S. Centers for Disease Control and Prevention. [...] influenza viruses constantly mutate, and it's possible for a strain to become more virulent, more resistant to drugs or more easily transmissible."
