What should you know about dengue cases worldwide?

Dengue is transmitted by infected mosquitoes, so risk changes with travel destination, local mosquito activity, weather, housing, and protection from bites. A person may become unwell during travel or after returning home. Fever, headache, muscle aches, joint pain, chills, rash, nausea, or easy bruising can occur, but symptoms alone cannot separate dengue from every other infection. Worldwide figures describe populations and places; they are not a personal diagnosis or a measure of your individual outcome.

Before and during travel, use repellent, long clothing, window screens, and a mosquito net where needed. After returning, tell a clinician where you travelled and when symptoms began. If you develop fever or body aches, rest, drink fluids, and arrange a GP Consultation, particularly if the destination has dengue transmission. While unwell, continue bite prevention so local mosquitoes are less likely to acquire virus from you.

Go to urgent care for severe abdominal pain, repeated vomiting, bleeding, black stools, blood in vomit, breathing difficulty, fainting, confusion, severe weakness, or very low urine output. Do not rely on global case information to decide that symptoms are harmless. A clinician may need to review you promptly even when fever changes or begins to improve. Seek earlier advice if pregnancy, childhood, older age, dehydration, or another illness could complicate care.

Ask whether your destination and symptoms warrant testing, which pain relief is appropriate, how to maintain hydration, and what warning signs should trigger emergency care. Provide your travel dates, accommodation details, bite exposure, and medicines.
