Congress MP Shashi Tharoor raised concern over the rising cases of Primary Amoebic Meningoencephalitis (PAM), caused by "brain-eating amoeba", in Kerala, urging people to avoid untreated freshwater. "It's a very sad story. A lot of people have caught this fatal virus by swimming in the freshwater," he said. He added, "Don’t go in freshwater," as 19 deaths have been reported.
