Signs and symptoms of fever
A fever is temporary as the body temperature rises due to an infection or any other secondary cause. It is a sign that something is going on within the body that needs to be looked into.1
Usually adults with a fever may feel uncomfortable and it is not much of a concern unless the temperature reaches 39.4°C or higher.1 For children, a temperature of more than 38°C is indicative of a fever.2

Symptoms of fever in children1,2
Other than a raised temperature of more than 38°C, children may exhibit symptoms of fever differently from adults.1,2
Febrile children may not be as active or talkative as usual or may seem fussier, less hungry but thirstier. On touching the child, they may feel hot or warm.2
As in adults, other symptoms associated with the cause of fever will also be apparent.
