Karachi reports first Naegleria death

Karachi has reported its first confirmed death from Naegleria fowleri in 2026, after a 44-year-old man from Korangi 3½ succumbed to the rare but deadly brain-eating amoeba during treatment.

According to hospital officials, the patient was admitted to a private hospital on July 5 after experiencing a high fever, severe headache, and neurological complications. Following a series of medical examinations and laboratory tests, doctors confirmed Naegleria fowleri infection on July 6.

As the infection rapidly spread to the brain, the patient’s condition deteriorated significantly. He was shifted to the hospital’s intensive care unit (ICU) and placed on a ventilator due to severe brain inflammation. Despite intensive medical treatment, doctors were unable to save his life.

Family members said the deceased was the father of two children and had no recent history of domestic or international travel. They also confirmed that he had not visited any swimming pool or water park, which are often associated with Naegleria infections.

According to the family, doctors believe the infection most likely occurred when contaminated water entered the patient’s nose during wudu, allowing the amoeba to travel to the brain. Naegleria fowleri infects people through the nasal passages and does not spread by drinking contaminated water or through person-to-person contact.

The Sindh Health Department confirmed that this is the first reported Naegleria case and first fatality in Karachi for 2026. Last year, the province recorded seven confirmed cases of the infection.

Medical experts explain that Naegleria fowleri is a microscopic amoeba commonly found in warm freshwater sources, including lakes, ponds, and poorly chlorinated water systems. Once the organism enters the body through the nose, it can travel to the brain and cause Primary Amoebic Meningoencephalitis (PAM), a rare but almost always fatal brain infection.

Symptoms typically begin with fever, headache, nausea, and vomiting before progressing rapidly to confusion, seizures, loss of consciousness, and severe neurological damage. Because the disease progresses quickly, early diagnosis and treatment remain extremely difficult and there is currently no consistently effective cure.

Following the latest fatality, health experts have urged residents to take preventive measures by ensuring that household water tanks and storage systems are properly chlorinated. They also recommend avoiding the entry of water into the nose during ablution or other activities involving untreated water, particularly during the hot summer months when the amoeba is more likely to thrive.

Authorities continue to raise public awareness about the importance of safe water practices to reduce the risk of future Naegleria infections.
