The organisms' expanded range may be due to increased temperatures from climate change.
Deadly "
brain-eating amoeba" infections have historically occurred in the Southern United States. But cases have been appearing farther north in recent years, likely because of
climate change, a new study finds.
The study researchers, from the Centers for Disease Control and Prevention (CDC), examined cases of this brain-eating amoeba, known as
Naegleria fowleri, over a four-decade period in the U.S. They found that, although the number of cases that occur each year has remained about the same, the geographic range of these cases has been shifting northward, with more cases popping up in Midwestern states than before.
