Bird flu has been around for about three decades, but a recent spike in cases in humans has some experts concerned. Former Baltimore Health Commissioner Dr. Leana Wen said on “Face the Nation” Sunday, “So, we’ve already seen this year that there have been a number of mammalian species close to humans that now have bird flu outbreaks. We have outbreaks in poultry in all 50 states.”
Sixteen states also have bird flu outbreaks in cattle, Wen added. “In California, in the last 30 days, there have been more than 300 herds that tested positive, and now we have 66 cases of bird flu in humans,” she continued.
