Bird flu is continuing to spread in animals across the United States more than a year after the first human case was detected.
Since then, at least 70 people have fallen ill and at least one death was recorded in Louisiana, according to the Centers for Disease Control and Prevention.
The number of confirmed cases in humans has held steady for almost two months, but hundreds of dairy cows continue to be infected and raw milk samples in several states have tested positive for bird flu, according to federal health officials.
