The US state of Texas has stepped up efforts to counter the threat posed by, Naegleria fowleri, a microscopic brain-eating amoeba, detected in the water supply of a coastal county that led to the death of a six-year-old boy earlier this month. Al Jazeera quotes the US Centers for Disease Control and Prevention as saying that the single-celled organism is commonly found in warm freshwater and soil, and it usually infects people when it enters the body through the nose, travelling up to the brain where it causes a rare and often deadly infection. Although infections from Naegleria fowleri are rare, the death rate is more than 97 percent and only four people out of 145 known infected individuals in the US from 1962 to 2018 have survived.
