Patient's question:
Female baby, 11 months old. Since yesterday morning, she showed signs of fever, with multiple temperature readings around 38.2°C in the afternoon, without other obvious symptoms (such as cough or runny nose). By evening, her temperature dropped below 38.5°C, and after taking ibuprofen, her temperature returned to normal within about half an hour.This morning, she again had a fever around 38.2°C. She was taken to the hospital for a finger-prick blood test (see attached image). The clinical diagnosis confirmed acute upper respiratory infection. The doctor prescribed some medication and said the condition might last for about 3 days. In the afternoon, when she returned home, her temperature continued to rise to 39°C. After taking ibuprofen again, within about half an hour, her temperature did not rise further.
How should this situation be resolved? Additionally, can the finger-prick blood test results rule out blood diseases, such as leukemia? Since we live in a newly renovated house (2 months ago) and have kept the windows open throughout, we are concerned about the potential interference of formaldehyde on the baby. Please help clarify this for me, thank you.
Doctor's answer:
Recurring high fever, no other obvious symptoms, laboratory tests show a decrease in white blood cells and neutrophils, normal white blood cell morphology, and almost no possibility of leukemia. The most likely cause is roseola in infants, caused by human herpesvirus transmission, with fever lasting for 3-5 days followed by the appearance of rashes after the fever subsides.This is the advice for the question "What should I do if my 11-month-old girl has fever symptoms starting from yesterday morning?" I hope it helps you. Wishing you good health and happiness every day!
