A fever that does not go down at 37.5°C does not necessarily mean that it is a new type of pneumonia. In addition to a persistent low-grade fever, novel pneumonia can also be accompanied by a dry cough and fatigue. Patients need to check themselves to see if they have recently visited an area with a high incidence of the disease or been in contact with a high-risk group of people, and to make a judgment based on a combination of factors. If the above-mentioned conditions exist, it is possible that the patient is infected with novel pneumonia and needs to be seen at a fever clinic for nucleic acid testing and to be isolated to avoid contact with others. In addition to new pneumonia, many clinical diseases can cause patients to have symptoms of 37.5℃ all the time, such as viral flu, bronchitis, bronchiectasis, pneumonia, tuberculosis, etc. It is recommended that patients can go to the hospital in a timely manner to clarify the cause of the disease, and then under the guidance of the doctor for professional treatment of the cause. If the state of 37.5℃ persists all the time, the fever can be relieved by physical cooling, such as warm water baths and antipyretic patches, etc. During the period, pay attention to drink more water and avoid getting cold. If the body temperature continues to rise, after physical cooling has no effect, and accompanied by dizziness, fatigue, dry mouth and throat and other uncomfortable symptoms, then you need to help reduce fever by oral antipyretic drugs such as ibuprofen and acetaminophen under the guidance of a professional doctor.
