Low fever is clinically known as hypothermia, which refers to a body temperature between 37.3℃ and 38℃. The treatment plan needs to be formulated according to the cause of the disease, such as environmental factors, upper respiratory tract infection, etc., and general treatment and oral medication are usually given. 1. Environmental factors: patients stay in a hot environment for a long time or wear too much clothing, these factors may lead to the body’s heat dissipation is affected, resulting in the patient’s body temperature is higher than 37.3 ℃ or more, but usually does not exceed 38 ℃. Usually do not need to take special treatment, it is recommended that patients in the high temperature environment to reduce clothing, which is conducive to the body’s heat dissipation, the body temperature naturally fall to normal. 2. Upper respiratory tract infections: patients with hypothermia is mostly caused by cold or pathogenic microbial invasion, causing dysfunction of the body’s thermoregulatory center, so that the body temperature rises to 37.3 ℃ ~ 38 ℃ or so. Usually, we should give patients alcohol rub, bath physical cooling, if necessary, can follow the doctor’s instructions to take amoxicillin capsules and other antibacterial drugs, amantadine hydrochloride and other antiviral drugs.
