Question
What diseases can cause persistent low fever?
Answer
A variety of different diseases can trigger high fever. Fever is a symptom that may be caused by conditions such as rheumatism, tuberculosis, chronic inflammation, and immune system abnormalities; long-term psychological stress and emotional fluctuations can also lead to disordered body temperature centers. Unexplained persistent low fever may be a sign that any body system is experiencing issues. The cause of high fever is sometimes difficult to detect through routine blood, urine, and stool tests, and fever caused by certain bacterial infections may require bacterial culture for confirmation. It is important to visit the hospital as soon as possible for a comprehensive examination. Early symptoms of many malignant tumors and initial symptoms of bacterial infections may also present as high fever.
