What should you know about dengue background?

Dengue virus is passed to people through the bite of an infected mosquito. Many bites are easy to miss, so the absence of a noticeable mark does not rule it out. The illness commonly causes fever with headache, muscle aches, joint pain, chills, or profound tiredness.

A rash, nausea, or mild bleeding such as nose or gum bleeding can also occur. These features are not unique to dengue. A clinician considers the pattern, local exposure, travel history, examination findings, and sometimes blood testing before making a diagnosis.

Rest and take frequent fluids, including oral rehydration drinks if advised. Keep a record of temperature, vomiting, urine output, and any bleeding. Check before taking pain relief: aspirin and ibuprofen are generally avoided when dengue is possible because they can worsen bleeding. Paracetamol may be suitable for some people, but follow local medical advice and the label.

Use mosquito screens, long sleeves, and repellent during illness. This helps reduce the chance that another mosquito becomes infected after biting you. Book a GP Consultation for assessment if dengue is possible.

Go to urgent care for worsening abdominal pain, repeated vomiting, bleeding, black stools, fainting, confusion, unusual drowsiness, breathing difficulty, or inability to drink. A person may need prompt review even if fever has eased, particularly when new symptoms appear during that change.

Ask whether testing is appropriate, how to monitor hydration, which medicines to avoid, and what symptoms require emergency help. Mention travel, mosquito exposure, pregnancy, long-term conditions, and every medicine or supplement you take.
