"CDC Warns of Deadly Amoeba Risk from Nasal Rinsing"

The CDC has reported cases of Acanthamoeba infections resulting from nasal rinsing with unsterile tap water, leading to skin diseases and a rare brain infection called granulomatous amoebic encephalitis (GAE). Three out of 10 infected individuals died, all of whom had weakened immune systems. The CDC recommends using boiled, sterile, or distilled water for nasal rinsing to prevent such infections.
