The first thing you need to do is to cover your body with heat. Repeated fever of 38.5 degrees, often need to use antipyretic, but can not cover the heat, because covering the heat will easily lead to disturbances in the temperature center, not only can not be able to reduce the fever, but also easy to affect the dissipation of heat, in the fever often need to cooperate with the physical cooling, such as paste antipyretic stickers, warm water bath, etc., to help reduce the fever. In addition, recurrent fever can not simply use antipyretic drugs, need to clarify the causes of fever, such as respiratory tract infections or urinary tract infections need targeted treatment. Respiratory tract infections are mostly due to viruses, bacteria, mycoplasma; urinary tract infections are mostly due to bacteria, Mycoplasma urealyticum and so on. If repeated fever of 38.5 degrees should be timely to the hospital, identify the causes, targeted treatment, try not to deal with their own, to avoid delays in treatment.
