I am 14 by the way, and i know at least 2 out of the 3 people who died were under 18, i dont know if there was a reason for that, or if it was just chance, but i thought i would mention it.
How are you? You may be referring to Naegleria fowleri infection, a single-cell, microscopic organism found in such freshwater bodies as lakes, rivers, hot springs and, occasionally, in neglected, unchlorinated swimming pools. This can invade and attack the human nervous system may cause death. The initial symptoms include, but are not limited to, changes in taste and smell, 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 over 3 to 7 days. Check with your doctor if you have these symptoms and to ease any anxiety. Take care and do keep us posted.
