Hi, Thanks for using healthcare magic. I have gone through your available history. It seems that your friend has developed infection likely to be viral in nature. You should take her to physician for detailed evaluation and management rather than just taking paracetamol. Doctor may advise you to go for blood tests like hemogram, Smear examination , urine examination etc to find out the cause of fever. Treatment should be directed as per cause. She should continue to take plenty of fluids and light diet to maintain her hydration. I hope It will help you. Thanks.
