Mosquito-borne encephalitis has killed 110 children in the southern Indian state of Andhra Pradesh in the past six weeks, health officials said Tuesday. Most of the victims were poor, malnourished children from rural areas who may have succumbed because of a sudden change in weather from intense summer heat to monsoon rains. P. Laxmi Rajyam, the state’s director of health services, said the meningo-encephalitis, which causes inflammation of the brain, has affected at least 196 children across the state.
