###Human: How can fever be treated in a baby? ###Assistant: Hi. In view of such high-grade fever in such a small child, I would advise you to take the child to the nearest pediatrician in order to get the child physically evaluated and blood investigations like CBC, CRP (and others as per physical examination be done). Though the WBC count was 12000 last week they may have increased now since the fever is a little high (40 degrees). Also the antibiotics given previously may need to be changed) stepped up. As of now to bring down the fever you can do tepid sponging.
