What is the fever cycle of type A influenza in children?

The fever cycle of pediatric influenza A varies due to individual differences, but generally includes the following stages: 1. **Fever onset**: After a child is infected with influenza A, the first symptoms typically appear within 1 to 4 days post-infection, with fever being the most common initial symptom. 2. **Peak fever phase**: During the early stage of the flu, body temperature gradually rises and may reach as high as 39°C to 40°C. This phase usually lasts for 2 to 3 days. 3. **Fever remission phase**: Following the peak phase, body temperature gradually declines but may persist for several more days, typically 1 to 3 days. During this stage, symptoms also begin to subside. 4. **Overall duration**: Taken together, the fever cycle of pediatric influenza A generally lasts 3 to 5 days, although it may persist longer, even beyond a week. If a child's fever lasts more than 5 days or symptoms worsen, prompt medical attention is recommended. 5. **Individual variation**: The fever cycle can vary depending on the child's physical condition and the effectiveness of medications used. Parents should closely monitor their child's condition and consult a physician when necessary.
