When to consult a doctor for fever?

If the fever is high or lasts several days

See a doctor if your fever lasts more than three days or is very high (above 39.4°C or 103°F), as this may indicate a more serious infection.

If severe or unusual symptoms occur

Seek medical attention if the fever is accompanied by chest pain, difficulty breathing, persistent vomiting or diarrhoea, rash, severe headache, neck stiffness, confusion, or seizures.

If you are at higher risk or symptoms worsen

Consult a GP if the fever occurs in an infant under three months old, if you have a weakened immune system or chronic illness, if you’ve recently travelled abroad, or if the fever continues to worsen over time.

Causes

It is important to understand the underlying cause of the fever to diagnose and treat it correctly. Here are some common types of fever:

Viral infections: Such as colds, flu, COVID-19, and other respiratory infections.

Bacterial infections: Such as tonsillitis, pneumonia, and urinary tract infections.

Chronic illnesses: Such as rheumatoid arthritis and ulcerative colitis, which can lead to prolonged fevers.

Tropical diseases: Such as malaria, dengue, and typhoid fever, often cause recurring fevers.

Heat stroke: Causes fever without sweating.

Medication reactions: Some individuals may experience fevers as a side effect of specific drugs.

Others: Some other fevers are found in Australia such as Q Fever or Australian spotted fever (Tick bites).

Warning signs for child fever

When it comes to fever in children or fever in babies, it’s essential to consult a doctor if:

A baby under three months has a fever above 38°C

A baby between three to six months has a fever or appears unusually irritable, lethargic, or uncomfortable.

The fever lasts more than three days

Your child shows signs of dehydration, difficulty breathing, persistent vomiting or diarrhoea, rash, or is unusually sleepy or unresponsive.

The fever is accompanied by a seizure, stiff neck, or severe headache.

Home remedies
