A four-year-old boy suffering from viral influenza had a persistent fever for four days. However, the fever kept recurring, and after a blood test at the hospital, it was discovered that his platelet count had dropped to 53 (normal range is 100-300), with a CRP of 11 and a reticulocyte count of 0.4. The platelet count has not yet recovered. Should artificial intervention be used to prevent chronicization or medication be taken? This will be known after the blood test. The most common platelet-reducing disease in children is idiopathic thrombocytopenic purpura, an unexplained blood system disease often related to the immune system. It is recommended that you take your child to a local regular hospital for a bone marrow biopsy first for diagnosis before treatment!
