Missouri reports a rare brain infection linked to lake activity

A Missouri patient is hospitalized with a confirmed Naegleria fowleri infection after visiting Lake of the Ozarks.

Rare brain-eating amoeba infection possibly linked to water skiing confirmed in Missouri

A Missouri resident is in intensive care with a confirmed Naegleria fowleri infection after spending time at the Lake of the Ozarks. Health officials said the illness may be linked to water exposure during activities such as water skiing and are investigating the source while noting the lake has two public beaches listed by the state park. Naegleria fowleri is a rare brain-eating amoeba that lives in warm freshwater and can infect people who force water up the nose. The Centers for Disease Control and Prevention explains that the infection, called primary amebic meningoencephalitis, is extremely uncommon but deadly. Since 1962, 167 cases have been reported in the United States. Last month a 12-year-old died in South Carolina after a similar infection, prompting families to speak publicly about the risk. To lower risk, officials advise nose protection during diving or jumping into water and caution that water entering the nose can cause infection. Symptoms can include nausea, fever, severe headache, stiff neck, seizures, changes in mental state, and hallucinations. It is not spread by swallowing water or by contact with an infected person.

This incident highlights how recreational water safety remains a delicate balance between enjoyment and health. Public health messaging must be clear and timely so people know how to protect themselves without dampening outdoor life. The case also underscores the ongoing challenge for local authorities to monitor popular lakes and communicate risks without triggering unnecessary alarm. In a climate of warmer waters and longer seasons, the potential for exposure grows, making practical guidance essential for lake communities across the state.
