NIH releases a Naegleria advisory.

There have been reports of Naegleria infections and deaths in Pakistan since 2008, per the alert. A number of places, including Karachi, are reporting cases of brain-eating amoeba, according to the advice.

An elevated temperature, headache, nausea, and stiff neck are signs of Naegleria, according to the advice. The virus may cause coma in the last stages of clinical manifestation, the NIH advised.

It is recommended that the department responsible for water supply make sure the water is treated with the recommended quantity of chlorine. Inadequate chlorine in water, particularly in hot weather, can lead to Naegleria, according to the alert.

Lakes, rivers, and hot springs are potential habitats for brain-eating amoeba. It explained in the advice that the infection happens when water with too little chlorine gets inside the nose. The NIH caution stated that waiting to diagnose the infection can result in mortality in 4–7 days.

75% of Naegleria cases are diagnosed after death, according to the NIH warning. It stressed in the alert that naegleria cannot survive in cold, clean, chlorinated water. Water tanks and pipes must be kept clean, per instructions sent to the appropriate authorities.
