Question
Since May 25th, a patient has been experiencing a persistent fever and has been receiving intravenous fluids and medication treatment for upper respiratory tract infection until May 31st. Subsequently, after blood tests and other symptom assessments, the patient was diagnosed with Kawasaki disease on May 31st. However, the blood test results showed a low white blood cell count. How should this situation be explained?
Answer
The recurrence and treatment of Kawasaki disease are indeed quite challenging, but fortunately, its recurrence rate is relatively low, approximately only 2%. Therefore, parents should pay special attention to their child’s care during the recovery period to avoid causing fever, as this is detrimental to the recovery of Kawasaki disease and may also affect the child’s overall health. Low fever can be caused by various diseases, with fever itself being a symptom that may be related to rheumatism, tuberculosis, chronic inflammation, low immunity, and other conditions. In addition, long-term psychological stress and emotional instability may lead to a disorder in the body’s temperature center, thereby causing persistent low fever. What is most important is to identify the root cause of the low fever.
