What should you know about dengue detection?

A clinician looks for an illness pattern that may include fever, headache, muscle aches, joint pain, chills, nausea, or a rash. Easy bruising or bleeding needs particular attention. These features can occur with other infections, so symptoms alone do not confirm dengue. Tell the clinician when the illness began, where you have been, whether mosquitoes were present, and which medicines you have taken.

Testing may involve a blood sample. The useful test can depend on how long symptoms have been present, and a clinician may also check blood counts or repeat an assessment to watch for changes. A negative early result does not always settle the question.

Arrange a GP consultation if dengue is possible, especially after travel or mosquito exposure in an area where it occurs. Rest, drink frequent fluids, and record your temperature and symptoms. Use only medicines recommended by a clinician or pharmacist; avoid aspirin or ibuprofen until a clinician has advised that they are suitable, because they may increase bleeding risk in some illnesses. Prevent further mosquito bites while unwell by using screens, covering skin, and following local advice.

Seek urgent medical help for severe abdominal pain, repeated vomiting, bleeding from the nose or gums, blood in vomit or stool, marked drowsiness or restlessness, trouble breathing, fainting, cold or clammy skin, or inability to drink. Warning signs can appear as fever settles, so feeling cooler is not a reason to ignore new or worsening symptoms.

Ask which test is appropriate today, whether it needs repeating, which pain or fever medicines are suitable, how much fluid to take, and which changes should prompt immediate review.
