Introduction
Influenza refers to the flu. Symptoms of the flu in children include nasal congestion, runny nose, fever, cough, nausea, vomiting, and muscle pain. If a child's symptoms continue to worsen or signs of complications appear, prompt medical attention is necessary. Meanwhile, parents should take preventive measures, such as maintaining good hygiene habits and increasing physical activity, to reduce the risk of children contracting influenza.

Generally speaking, influenza refers to the flu. Symptoms of the flu in children include nasal congestion and runny nose, fever, cough, nausea and vomiting, and muscle pain, among others. A detailed analysis is as follows:

1. Nasal Congestion and Runny Nose

Influenza virus may adhere to the nasal mucosa, invade mucosal cells, cause nasal mucosal congestion and edema, trigger local inflammatory reactions, and lead to runny nose. This may cause breathing difficulties in children, particularly noticeable during nighttime sleep.

2. Fever

Influenza virus replicates within the child's body, stimulating the immune response to release pyrogens that act on the body's temperature regulation center, causing the body temperature to rise above 39℃ for several days, accompanied by chills and shivering.

3. Cough

Influenza virus reproduces within respiratory epithelial cells, triggering inflammatory responses that stimulate respiratory mucosal secretions, leading to cough reflexes accompanied by sore throat or discomfort. In severe cases, it may affect the child's eating and speaking abilities.

4. Nausea and Vomiting

Influenza virus may attack gastrointestinal mucosa, causing gastrointestinal dysfunction. Some children may experience nausea, vomiting, and other gastrointestinal symptoms, leading to poor appetite, further affecting nutrient intake and recovery.

5. Muscle Pain

Influenza virus may lead to the accumulation of metabolic products such as lactic acid in the body. Inflammatory reactions caused by the virus may stimulate nerve endings, resulting in generalized muscle or joint pain in children, along with muscle stiffness and a feeling of weakness, affecting the child's daily activities.

If a child's symptoms continue to worsen or show signs of complications, timely medical treatment should be sought. At the same time, parents should take preventive measures, such as maintaining good hygiene habits and encouraging physical exercise, to reduce the risk of children contracting influenza.

How long after a head injury should a CT scan be performed?
If there is only mild headache without other discomfort after a head injury, it is generally safe to observe at home for 24 hours. If symptoms do not worsen during this period, urgent CT scan is usually unnecessary. However, for children, elderly individuals, or those with underlying medical conditions, even mild symptoms warrant a CT scan within 6–12 hours after the injury to rule out potential risks. Immediate severe headache, frequent vomiting, or similar symptoms after a head injury require prompt medical attention.
