What should you know about a chikungunya virus outbreak?

During local transmission, mosquito protection becomes especially useful for everyone, including people who feel well. Someone who becomes infected may develop sudden [Fever](/symptoms/fever/), marked [Joint Pain](/symptoms/joint-pain/), [Muscle Aches](/symptoms/muscle-aches/) or a rash. Symptoms can overlap with other mosquito-borne illnesses, so an outbreak setting adds context but does not establish the diagnosis by itself.

Use repellent as directed, wear clothing that covers arms and legs, and keep doors, windows and sleeping areas screened when possible. Remove standing water from containers around the home because it can support mosquito breeding. If you become unwell, limit mosquito exposure while symptoms are present so a mosquito is less likely to acquire the virus from you. Contact a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) service for advice about assessment and local guidance.

Seek medical advice for a new fever after possible exposure, particularly when joint pain, muscle aches or rash accompany it. Get urgent help for trouble breathing, fainting, confusion, severe weakness, inability to keep fluids down, or unusual bleeding. Do not wait for an outbreak announcement if symptoms are severe; urgency depends on the person’s condition.

Ask what local exposure information is relevant, whether your symptoms need testing, how long to avoid mosquito bites while ill, which medicines are appropriate, and which warning signs should prompt urgent review.
