So the amoeba is crawling up the nerve and gets into the brain." "At the top of the nose you have a little paper-thin plate made of bone with a bunch of holes, a little bit like a mosquito net," Ratard said. "To get infected, the amoeba has to get to the ceiling of your nose – way, way up there," the late epidemiologist Raoult Ratard told NPR in 2013, when the amoeba was found for the first time in a city water supply in the U.S. Infections in humans are devastating but rare. But the amoeba mainly eats bacteria, not brains, and those organisms are plentiful in the sediment of lakes and rivers. Naegleria fowleri is commonly known as the "brain-eating amoeba" - and it does indeed destroy brain tissue. Here are five things to know about the microscopic brain-eating amoeba:

NPR contacted the Missouri Department of Health on Monday for an update on the patient's condition and other details, but had not received a response at the time of publication. But it added, "Additional public water sources in Missouri are being tested." "It's strongly believed by public health experts that the lake is a likely source," Missouri's health department said on Friday. The state agency is also in contact with the Missouri Department of Health, an Iowa representative told NPR. Iowa's Department of Health and Human Services says it's working with the CDC to confirm whether Naegleria fowleri is present in the lake - a process that takes several days. The person was visiting from Missouri, which is just over the border from the park in Iowa's southwest. "Only four people out of 154 known infected individuals in the United States from 1962 to 2021 have survived."ĭetails about the Iowa case have not yet been released. "The fatality rate is over 97%," the Centers for Disease Control and Prevention says of PAM infections. It's both extremely rare - and extremely deadly. Iowa officials closed the beach at Lake of Three Fires State Park on Thursday after confirming that a person who swam there was infected with Naegleria fowleri, an amoeba that causes a disease called primary amebic meningoencephalitis (PAM). Add the fact that it kills most people it infects - and that while infections are rare, the parasite is fairly common - it's not surprising that a confirmed case of Naegleria fowleri infection in a swimmer in Iowa is drawing attention.
