Not everyone with pneumonia will have a fever. Although the typical symptoms of pneumonia are chills and high fever, some older or weaker people with pneumonia do not present with fever. Pneumonia in the elderly mainly presents with indifferent expressions, decreased appetite, dyspnea, and abdominal pain, and is not dominated by fever or even significant coughing or phlegm. Pneumonia in the elderly should be considered when elderly people with reduced mobility have recently developed depression, decreased appetite, shortness of breath, and dyspnea. Patients with pneumonia may not have fever as the main symptom, but if the patient is accompanied by fever go to the hospital for relevant examinations in a timely manner. If a low fever is present, it can be managed by drinking more water and taking oral antipyretics. If there is a high fever or some accompanying symptoms, such as chills, abdominal pain, cough, coughing, etc., go to the hospital for further examination such as chest X-ray and CT, and you need to go to a specialist in time.
