An avian flu outbreak in the U.K. is just the latest to erupt across the globe, worrying health experts about the possibility that the virus could become more widespread.
Today U.K. officials confirmed a fifth area in the country has been hit with the H5N8 strain of the avian flu, since December. The strain has been spread from wild birds to farmed poultry, but has yet to affect humans, according to the U.K. Department of the Environment.
