Patient's question:
Doctor, my son is 8 months old. He had a fever for 3 days after getting the measles vaccine 4 days ago. After the fever subsided, he broke out in a rash 1 day later. Today is the 4th day, and his condition has not improved. His white blood cell count is 3.7, with a neutrophil absolute value of 1.4. What could be the cause, and what illness might this be? Please help us analyze this. Thank you.Doctor's answer:
Emergency care for infants and children, don't hurry, it will be okay. Low white blood cell count is due to a viral infection. White blood cell reduction is related to multiple factors, such as recent infection, frequent hair dyeing, exposure to toxic and harmful substances like paint, renovation materials, newly renovated furniture, etc. Additionally, taking certain medications such as chemotherapy drugs, medications for hyperthyroidism, etc., can also cause white blood cell reduction. Secondly, blood system diseases may also lead to low white blood cell counts. It is recommended to further examine the condition to identify the cause and receive appropriate treatment.
