Patient's question:
Female baby, 11 months old. From yesterday morning showing signs of fever to the afternoon, multiple temperature readings were around 38.2 degrees Celsius, without other obvious symptoms (including cough, runny nose, etc.), and by the evening, the temperature dropped below 38.5 degrees Celsius. After taking ibuprofen, the temperature returned to normal after about half an hour. This morning, she again had a fever of around 38.2 degrees Celsius. She was taken to the hospital for a finger blood test (see attached image), and the clinical diagnosis confirmed acute upper respiratory infection. The doctor prescribed some medication, saying that this condition might last for about 3 days. In the afternoon, when she returned home, her temperature continued to rise to 39 degrees Celsius. After taking ibuprofen again, about half an hour later, her temperature did not rise further. How should this situation be resolved? Additionally: Can the finger 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 interference of formaldehyde on the baby. Please help me understand this, 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 and rash appearing 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!
