What should you know about dengue fever locations?

Dengue is spread by infected mosquitoes, not by simply being near a person who is ill. A clinician will ask about recent travel, stopovers, outdoor time, accommodation, and mosquito bites. Transmission patterns can vary by place and season, so your location history helps guide the need for testing and observation.

After exposure, symptoms may include fever, headache, muscle aches, joint pain, chills, or easy bruising. These symptoms are not specific to dengue, and location alone cannot establish a diagnosis.

Write down the dates and places you visited, when symptoms began, and any mosquito protection you used. Arrange a medical assessment if fever or compatible symptoms develop after travel or mosquito exposure. Rest, drink fluids if tolerated, and use only medicines recommended by a clinician or pharmacist. Reduce mosquito bites while unwell by using screens, covering skin, and following local advice.

A GP consultation can help review your travel history, symptoms, examination findings, and whether a blood test or follow-up is appropriate.

Get urgent care for severe stomach pain, ongoing vomiting, bleeding, black stools, unusual sleepiness, confusion, breathing trouble, faintness, or difficulty drinking. Seek advice promptly if a child, older adult, pregnant person, or someone with a significant health condition develops fever after possible exposure.

Ask whether your travel locations are relevant, when testing is useful, how to prevent mosquito bites at home, which medicines to avoid, and how follow-up will be arranged.
