Introduction
Fever generally refers to elevated body temperature. In children, viral fever may be caused by viruses from the air, food, infected individuals, etc. Due to their relatively weak immune systems, children are susceptible to viruses present in the air, which can enter the respiratory tract through breathing and potentially cause respiratory infections leading to fever. Additionally, because children's gastrointestinal functions are not fully developed, gastrointestinal infections can also result in viral fever.
Fever generally refers to an elevated body temperature. Viral fever in children may originate from sources such as air, food, or infected individuals.
1. Air: Children have relatively weak immune systems. During seasons when viruses are prevalent, many viruses may be present in the air and can enter the respiratory tract through breathing, potentially causing respiratory infections that lead to fever.
2. Food: Children's gastrointestinal systems are not fully developed. If ingredients are contaminated with viruses or have spoiled, the viruses can enter the digestive tract through food, causing gastrointestinal infections and resulting in viral fever.
3. Infected individuals: If a child has close contact with someone suffering from a viral infection such as the common cold, the virus may spread via respiratory droplets or oral transmission, leading to infection and subsequent fever.
It is recommended to avoid prolonged stays in crowded areas, wear masks when going out, refrain from consuming spoiled food, and maintain good personal hygiene.
