A 71-year-old woman in Texas has died from a brain-eating amoeba after using tap water to rinse her sinuses. According to the CDC, this incident has raised alarms regarding the safety of using untreated water for nasal irrigation. The woman reportedly used tap water from an RV campground, which has been linked to the presence of the amoeba. Health officials are urging the public to avoid using tap water for nasal rinses unless it has been boiled or treated, as summer months pose an increased risk for these rare infections. As awareness of this deadly parasite spreads, many are questioning the safety of water sources in recreational vehicles and campgrounds.
