The deadly ‘brain-eating amoeba’ has expanded its reach north

Deadly ‘brain-eating amoebaIn the past, infections have occurred in the southern United States, but cases have occurred further north in recent years, probably due to climate change, a new study finds.

The study’s researchers, from the Centers for Disease Control and Prevention (CDC), examined cases of this brain-eating amoeba, known as Naegleria fowleri, over a period of four decades in the U.S. They found that while the number of cases that occur each year has remained about the same, the geographic range of these cases has shifted north, with more cases emerging in states in the U.S. Midwest than before.
