Brain-eating threat

Dubbed as a 'brain-eating amoeba', Naegleria fowleri has claimed yet another life in Sindh, bringing the total tally of the province up to five this year. The most recent unsuspecting victim, a 29-year-old male resident of Karachi, was not even diagnosed before his demise. The young man unfortunately passed away merely four days after experiencing symptoms, and laboratory tests confirmed the cause a day after the patient's death. Not only are these details spine-chilling, but they serve as a blaring call for precaution against this deadly amoeba that is only preventable, not curable.

The survival rate of Naegleria fowleri is less than 5% globally, with certain drug combinations being completely ineffective in humans despite killing the amoeba in a laboratory setting. With no known cure, the most effective method of prevention is to strictly use chlorinated or treated water for nasal rinsing, as the amoeba enters the brain by traveling up the olfactory nerves in the patient's nose. Water bodies such as lakes and rivers are also hotspots for infections; therefore, it is important to avoid swimming or diving in such places lest it causes nasal exposure or inadvertent contact with contaminated water.

The authorities should assume responsibility for chlorinating water at all water storage facilities to keep the amoeba at bay. Health officials clarify that the most recent victim of the disease had not partaken in any "water-related activities" and was most likely infected through tap water. Therefore, the Karachi Water and Sewerage Corporation must once again be instructed to perform due diligence as precaution is necessary at both personal and institutional levels. As the disease rapidly progresses and transforms into a fatal tragedy, it is best to err on the side of extreme caution and prevention.
