Question
What should be the normal body temperature of a four-month-old child?
Answer
The normal baseline body temperature for a four-month-old baby is approximately 36.9℃ to 37.5℃. Generally, a temperature that is 1℃ higher than the baseline can be considered a fever. Low fever is defined as a temperature around 38℃, while high fever refers to a temperature above 39℃. Continuous fever lasting over two weeks is known as prolonged fever. It is recommended to first have a doctor diagnose whether it is a viral or bacterial infection. For viral infections, antiviral medications (such as ribavirin) may be used, and for bacterial infections, antibiotics (such as cephalosporins) may be prescribed. Do not rush to lower the fever, as fever is just a symptom; it is important to find the true cause of the illness.
