Explanation

Brain-eating amoeba infection, caused by Naegleria fowleri, is a rare but severe condition. Symptoms often start with headache, fever, nausea, and vomiting. As the infection progresses, more serious symptoms can appear, such as confusion, loss of balance, seizures, and hallucinations.

These symptoms usually begin 1 to 9 days after exposure to contaminated water. The infection progresses rapidly, often leading to death within 1 to 18 days after symptoms start. It's important to seek medical attention immediately if these symptoms appear after swimming in warm freshwater.

The infection occurs when water containing the amoeba enters the body through the nose. It is not spread from person to person. While rare, the infection is very serious and requires prompt medical treatment. Remember, early detection and treatment are crucial for survival.
