Question
A two-and-a-half-year-old baby has had a fever every night for four consecutive days, with no fever during the day. For the past two days, there has been persistent dry vomiting, and today the baby is not throwing up but unsteady on their feet. The fever has started again at night, and the baby has been receiving injections for three days without any effect.
Answer
For the persistent fever in this two-and-a-half-year-old baby, it is recommended to first conduct a routine blood test to determine if there are any bacterial or viral infections, among other issues, so that symptomatic medication can be administered promptly. Also, be aware of any rashes that may appear. During a fever, if the body temperature is below 38.5 degrees Celsius, you can use fever-reducing medication; if it exceeds 38.5 degrees Celsius, physical cooling measures should be taken. Ensure plenty of water intake, consume warm and easy-to-digest foods, and pay attention to staying warm, especially keeping the abdomen warm. If the situation does not improve, it is advisable to go to the hospital for a detailed examination immediately, and intravenous treatment may be necessary if required.
