On Saturday morning, a 45-year-old man died in Kerala of amoebic meningocephalitis. This is the fourth death reported in Kerala in less than a month of this rare but deadly infection, colloquially known as brain-eating amoeba. This year alone, over 40 cases have been reported in the State, with 11 people undergoing treatment in hospitals at present. The Health Department has invoked the Kerala Public Health Act to launch preventive and control measures, as it emerges that perhaps all waterbodies — wells, ponds, canals, swimming pools, water theme parks — could be a potential source of amoebic infection for people using them, unless these are regularly cleaned and maintained in good condition. What is this brain-eating amoeba? Why is a rare infection being seen in dozens of people across one Southern state? How is it diagnosed and treated? And how can water be used safely?
