Kolkata, July 29 (ANI): CPI (M) leader Biman Bose hit out at West Bengal government over its inability to tackle Japanese Encephalitis. Almost 570 people in India have died after contracting encephalitis, commonly known as "brain fever", health authorities said on Friday, warning the death toll may rise with more people still at risk. In West Bengal, where at least 111 people have died from both strains, a senior health official said authorities were taking emergency steps to contain the outbreak. Bose attacked Chief Minister Mamata Banerjee, saying she was misleading people. The health department has set up clinics across affected areas and is trying to prevent breeding of mosquitoes by fogging, especially around pig farms, where there is a high risk of contracting the virus.
