St. Louis, MO, November 8, 2026 —

Louisiana health officials have reported a concerning increase in Acanthamoeba infections this year, with 10 cases identified since the beginning of 2024. These infections have led to severe consequences, including permanent vision loss for five individuals and a fatality resulting from a brain infection.

Acanthamoeba is a common microorganism found in water and soil. While infections are rare, they can be serious, particularly for those who wear contact lenses. The most common and severe form of Acanthamoeba infection affecting humans is Acanthamoeba keratitis, an infection of the cornea, the clear outer layer of the eye. This condition can cause significant pain and, if left untreated or if it progresses, can lead to irreversible vision impairment.

The state epidemiologist has issued a warning to the public, emphasizing the risks associated with exposure to water while wearing contact lenses. This includes tap water, swimming pools, hot tubs, and even showering or sleeping in lenses.

Experts advise that proper hygiene practices are crucial for contact lens wearers to minimize the risk of infection. These practices often include thorough handwashing before handling lenses, avoiding water exposure while wearing lenses, and replacing lens solution and cases regularly. Despite these precautions, the reported cases highlight the persistent threat of Acanthamoeba infections.

Further details regarding the specific timelines, locations within Louisiana, or the precise nature of the brain infection were not immediately available. The health department continues to monitor the situation and provide guidance to healthcare providers and the public to prevent further cases.
