Authorities have launched an urgent investigation after a rare water-borne "brain-eating" amoeba killed 10 people in four months, officials said Tuesday. The water company and health officials monitoring water in Karachi, home to 18 million people, have been ordered to trace the source of the Naegleria fowleri outbreak.
Saghir Ahmed, Sindh health minister, said the drinking supply, swimming places and facilities used for the ritual ablutions Muslims must perform before prayers were all under investigation. "There is no reason to panic and citizens should stay calm and take precautions," Ahmed said.
