What should you know about Aedes albopictus and dengue?

Transmission occurs when an infected mosquito bites a person. The species is often called the Asian tiger mosquito and can live in urban or garden settings where small water containers provide breeding sites.

Dengue can present with fever, headache, pain behind the eyes, muscle aches, joint pain, nausea or a rash. These features overlap with other infections, so neither a single symptom nor the appearance of a bite confirms the cause.

Aedes albopictus tends to bite in the daytime. Reducing standing water in plant saucers, buckets and uncovered containers helps limit breeding close to living areas.

For fever after possible dengue exposure, rest, drink fluids in frequent amounts and arrange clinical advice. Tell the clinician about recent travel, local mosquito exposure, when symptoms began and every medicine you have taken.

Avoid aspirin and anti-inflammatory pain medicines such as ibuprofen until a clinician has considered dengue because they can increase bleeding concerns. Paracetamol may be suitable for fever or pain when taken according to the label and when no health condition prevents its use.

Seek urgent care for severe abdominal pain, repeated vomiting, bleeding from the nose or gums, blood in vomit or stool, unusual bruising, breathing difficulty, confusion, pronounced weakness, fainting, cold clammy skin or very little urine. Warning signs can appear as fever begins to settle, so improvement in temperature alone is not enough to rule out deterioration.

Ask whether your symptoms and exposure fit dengue, whether tests are appropriate, how much fluid to aim for, which pain relief is safe for you and which specific changes require emergency care. Mention pregnancy, long-term illness or medicines that affect bleeding.
