The deadly “Brain-Eating” amoeba is slowly but surely expanding its footprint in the US

Historically, lethal “brain-eating amoeba” infections have occurred in the southern United States. But in recent years, cases have appeared further north, probably due to climate change, according to a new study.

Researchers at the Centers for Disease Control and Prevention (CDC) looked at cases of this brain-eating amoeba, known as Naegleria fowleri, for four decades in the United States.

They found that although the number of cases occurring each year remained about the same, the geographical range of these cases shifted north, with more cases occurring in the Midwestern states than before.
