Question
The child has been experiencing persistent low-grade fever, reaching up to 37.8 degrees Celsius (measured under the armpit). After taking traditional Chinese medicine, there was improvement, but the fever returned accompanied by sore throat and enlarged lymph nodes. The child had pulmonary tuberculosis before the age of three and is asking if it is related to the tuberculosis or another cause.
Answer
Low-grade fever can be a symptom of various diseases, including rheumatism, tuberculosis, chronic inflammation, immunodeficiency, and prolonged psychological stress can also cause confusion in the body’s temperature center leading to unexplained low-grade fever. Before the body temperature reaches 38 degrees Celsius, it is not recommended to use antipyretic drugs because misusing antipyretic drugs may pose risks such as a decrease in white blood cells and aplastic anemia.
