The infection in India is believed to have started in Kozhikode in Kerala, where dead bats were found in an unused well inside a home. Four members of the family that stayed there have died, including a man and his two sons.The symptoms of the infection include fever, headache, drowsiness, breathing trouble, disorientation and delusions. According to the World Health Organisation (WHO), these symptoms can progress to coma within 24-48 hours.
