Fever and Infections in Children
Overview
Fever is one of the most common reasons children require medical assessment. A fever usually means the body is responding to an infection or illness. Many childhood infections are mild and improve with supportive care, while others may require medical treatment or closer monitoring.
Children may develop fever alongside cough, congestion, vomiting, diarrhoea, sore throat, reduced appetite, tiredness, or irritability. Some infections are short-term and self-limiting, while others may become more serious if symptoms worsen or do not improve.
The focus is on identifying the possible cause of symptoms, supporting recovery, monitoring for complications, and helping families know when additional care is needed.
Symptoms
Children with fever or infections may experience symptoms that vary depending on the cause and severity of illness. Symptoms may include:
- Elevated body temperature or fever
- Cough or congestion
- Sore throat
- Vomiting or diarrhoea
- Reduced appetite
- Tiredness or weakness
- Irritability or reduced activity
- Body aches or discomfort
Some children may also experience breathing difficulties, dehydration, or worsening symptoms that require urgent assessment.
Causes & Risk Factors
Fever and infections in children may be caused by viral, bacterial, or other infectious illnesses. Children may be more likely to develop infections if they:
- Attend school or daycare settings
- Have close exposure to sick individuals
- Have weakened immunity
- Experience poor nutrition or dehydration
- Have underlying medical conditions affecting immunity or breathing
Many childhood infections spread easily through coughing, sneezing, or close contact.

You should seek medical assessment if your child:
- Has persistent or recurrent fever
- Appears unusually tired or weak
- Has difficulty feeding or drinking fluids
- Experiences vomiting or diarrhoea with dehydration

- Develops symptoms that are not improving
Emergency Symptoms
Seek immediate medical care if your child experiences:
- Difficulty breathing
- Severe dehydration or inability to drink fluids
