A parasite known as the "brain-eating amoeba" has claimed its second young American victim this month.

Christian Strickland, a 9-year-old from Henrico County in Virginia contracted an infection after visiting a fishing camp in his state. He died of meningitis on August 5.

This week, health department officials confirmed that the deadly amoeba--officially known as "Naegleria fowleri"--was to blame.

"Sadly, we have had a Naegleria infection in Virginia this summer," Dr. Keri Hall of the Virginia Department of Health, told The Richmond Times-Dispatch. "It's important that people be aware of . . . safe swimming messages."

Earlier this month, Courtney Nash succumbed to the brain-eating amoeba after diving off a dock into the St. John's River at her grandmother's house in Florida.

According to her mother Patricia Nash, Courtney decided before her death to become an organ donor. "I didn't get my miracle, but she has performed other miracles," Patricia told local station WESH. "If we can save other people's lives so they don't have to go through what I just went though, this could be a blessing in disguise."

Usually found in warm, stagnant water in freshwater lakes, ponds, and rivers, the parasite "enters the nasal passages ... and migrates to the olfactory nerves, eventually invading the brain," according to the Centers for Disease Control and Prevention. It almost always causes meningitis. Symptoms include fever, nausea, stiff neck and a frontal headache.

Thirty-two infections of the parasite were reported in the U.S. between 2001 and 2010, CDC spokeswoman Christine Pearson told The Lookout, adding that infections are almost always deadly. That included two children in Phoenix who are thought to have contracted it through the domestic water supply in 2002.

Naegleria fowleri (play /nəˈɡlɪəriə/; also known as "the brain-eating amoeba") is a free-living excavate form of protist typically found in warm bodies of fresh water, such as ponds, lakes, rivers, and hot springs. It is also found in soil, near warm water discharges of industrial plants, and minimally chlorinated swimming pools (there is no evidence of this organism living in ocean water) in an amoeboid or temporary flagellate stage. It belongs to a group called the Percolozoa or Heterolobosea. Although not a true amoeba, the organism is often referred to as an amoeba for convenience.

N. fowleri can invade and attack the human nervous system. Although this occurs rarely,[1] such an infection nearly always results in the death of the victim.[2]

simptoms:

Onset symptoms of infection start 1 to 14 days after exposure. The initial symptoms include, but are not limited to changes in taste and smell, also headache, fever, nausea, vomiting, and stiff neck. Secondary symptoms include confusion, hallucinations, lack of attention, ataxia, and seizures. After the start of symptoms, the disease progresses rapidly 3 to 7 days, with death occurring from 7 to 14 days...dalam masa 2minggu dia makan otak?eee

treatment?

It is not clear. Several drugs are effective against Naegleria fowleri in the laboratory. However, their effectiveness is unclear since almost all infections have been fatal, even when people were treated.

-semua kes berakhir dengan kematian?ada bran?eeee takut
