Hi there, Fever is a sign of infection. In your case, if you are also having flu-like symptoms (e.g. runny nose, cough, etc.), it might be related to viral infection. It will be reversed in a few days. If the fever will persist, and/or if the symptoms will be aggravated, should get further checked by your doctor to exclude possible pneumonia or other health problems. Meanwhile, I highly advise to: - consume more fluids (water, tea, juices) - have light meals (yogurt, curd, soups) - take good care of your throat (can do gargle with water and salt) - take 1 teaspoon of olive oil and honey on daily basis Wish fast recovery!
