Brain-eating amoeba: A 14-year-old boy, Mridul, has died from amoebic meningoencephalitis, a rare brain infection caused by a free-living "brain-eating" amoeba found in contaminated water, at a private hospital in Kozhikode. This marks the third such case in Kerala recently, following the deaths of a five-year-old girl from Malappuram on May 21 and a 13-year-old girl from Kannur on June 25.
