Patient's question:
The baby is nine and a half months old and has a fever for the first time. It started last night on November 14th, with a temperature above 38℃ and peaking at 38.7℃. We used physical cooling methods. Yesterday daytime was fever-free, but it started again last night, with a temperature above 38.5℃ but below 39℃. At 3 a.m., the fever reached 40℃, and after physical cooling, it dropped to 39.2℃. We gave the baby two milliliters of ibuprofen suspension, and the fever subsided around 4 a.m. By 7 or 8 a.m., it started fevering again, between 38.5℃ and 39℃, and we gave another two milliliters of ibuprofen suspension. Now the fever has dropped to 38.6℃. There are no cold symptoms, only fever, and the baby's mental state is excellent, eating and drinking normally. On November 12th, the baby received a vaccine to prevent hand, foot, and mouth disease. We kindly ask the doctor to make a prediction. Thank you very much.Doctor's answer:
In this case, it could be a vaccine reaction or possibly caused by a cold, in addition to being a possible case of roseola. We can only let the baby drink more water, rest more, and pay close attention. Generally, the fever will persist for about three days. If it's caused by a vaccine reaction, it will gradually subside after about three days. If it's caused by a cold, it's also usually about three days. If a rash reappears, then it should be considered a possible case of roseola.
