Clinical features of dengue

Dengue is an infection that can cause a febrile illness. [Fever](/symptoms/fever/) may occur with [Headache](/symptoms/headache/), pain behind the eyes, [Muscle Aches](/symptoms/muscle-aches/), and [Joint Pain](/symptoms/joint-pain/). [Chills](/symptoms/chills/) can accompany the fever. Some people develop nausea, a rash, or mild bleeding signs such as easy bruising. Symptoms can overlap with other infections, so a clinical assessment is needed to interpret the pattern and recent travel or mosquito exposure.

Rest, drink fluids regularly, and record temperature and changes in symptoms. Arrange a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) if fever is substantial, persistent, or follows travel to an area where dengue occurs. Tell the clinician about travel dates, medicines, bleeding, vomiting, and fluid intake. Avoid taking aspirin or ibuprofen unless a clinician specifically advises it, because some dengue illnesses involve bleeding risk; ask what fever relief is suitable for you.

Seek urgent medical care for severe abdominal pain, repeated vomiting, bleeding from the nose or gums, blood in vomit or stool, unusual drowsiness, breathing difficulty, faintness, or inability to drink. Easy bruising that is spreading or accompanied by other bleeding should be assessed promptly. Symptoms can change as fever settles, so worsening after an apparent improvement still needs attention.

Ask whether your symptoms and travel history fit dengue, whether testing is appropriate, which fluids and medicines are suitable, and how to monitor for bleeding or dehydration. Confirm when you should return for review.
