What should you know about classical dengue?

Dengue infection can begin with fever, chills, headache, pain behind the eyes, muscle aches, joint pain, nausea, or a rash. Easy bruising or bleeding can occur and should be reported. Symptoms may overlap with other infections, so a symptom pattern cannot confirm dengue by itself. A GP consultation can help decide whether examination or testing is needed, particularly after travel or residence in an area where dengue occurs.

Rest, drink fluids regularly, and keep a record of fever and other symptoms. Use only medicines recommended by a clinician or pharmacist; some pain medicines can increase bleeding risk and may not be suitable when dengue is suspected. Avoid mosquito bites while unwell by using screens, covered clothing, and an appropriate repellent, because mosquitoes can acquire the virus from an infected person. Do not donate blood until a clinician confirms it is appropriate.

Seek urgent medical care for severe abdominal pain, repeated vomiting, bleeding from the nose or gums, blood in vomit or stool, marked drowsiness, breathing difficulty, fainting, or inability to drink. Symptoms can become more concerning as the fever changes, so apparent improvement is not a reason to ignore new warning signs. Pregnant people, young children, older adults, and those with significant medical conditions should seek advice early.

Ask whether your symptoms and recent travel fit dengue, which pain-relief options are suitable, whether testing is needed, how to monitor hydration, and which changes should prompt immediate reassessment.
