This produces a serious type of fever called Abhinyaas jvara. The ears and the eyes become functionally inactive and the patient does not like to do any movement. Neither the eyes are capable of seeing anything, nor there any sense of smell, touch or sound. The patient keeps on shaking the head, doesnot relish any food, makes sounds like that of pigeon, feels pain as if pricked, desires change in posture and speaks very little and infrequently. Very few would survive from it.
