Mexican health officials have confirmed the presence of the notorious brain-eating amoeba, Naegleria fowleri, in six artificial lakes located in a popular tourist region of Yucatan. This precautionary measure follows the death of a water sports instructor who contracted the amoeba in September of the previous year, according to reports from the regional Health Secretariat.
The affected lakes, which are designed for recreational activities such as water skiing, paddleboarding, and kayaking, are situated within shopping malls and luxury residential areas. Yucatan is well-known for its beautiful Gulf of Mexico beaches, resorts, and ancient Mayan ruins.
This incident marks the first recorded death from this amoeba in the state, which is also famous for its cenotes—natural freshwater sinkholes and caverns formed by the collapse of limestone rock. In response, health officials have decided to enhance health monitoring in these areas.
Alberto Alcocer, the Yucatan Health Secretary, urged residents to seek medical attention promptly if they believe they have come into contact with contaminated water. He emphasized that the discovery of the amoeba does not indicate an epidemic, nor does it mean that individuals who visited these lakes are necessarily ill.
He explained that infection occurs when contaminated water enters through the nose, stressing the need for continued preventive actions. The deceased instructor had been hospitalized for several days before succumbing to primary amoebic meningoencephalitis, a serious illness caused by the amoeba.
Naegleria fowleri thrives in stagnant freshwater bodies, including lakes, rivers, and hot springs worldwide, particularly in temperatures ranging from 35 to 46 degrees Celsius, according to Mexican health officials. While brain infections from this amoeba are extremely rare, they are nearly always fatal.
The Yucatan government has launched an investigation into the companies responsible for maintaining water quality in the first lake where the amoeba was detected.
