What should you know about a dengue outbreak?

Outbreak information describes a population or location; it does not diagnose an individual. Dengue presents with symptoms such as fever, headache, muscle aches, joint pain and chills. A person with these symptoms may have another infection, while a person with dengue may need monitoring even when symptoms change.

The virus is carried by infected mosquitoes. During an outbreak, limiting bites becomes especially useful: use repellent as directed, wear clothing that covers skin, and reduce standing water around living areas. A mosquito can acquire the virus from an infected person and later transmit it to another person.

Check current local health advice if you are in an affected area, and contact a clinician if you develop a fever or compatible symptoms. Rest and maintain fluids. Tell the clinician about recent travel, outdoor exposure, mosquito bites and any medicines you take. Do not self-treat with aspirin or anti-inflammatory medicines without advice.

Get urgent care for severe belly pain, persistent vomiting, bleeding, black stools, breathing difficulty, faintness, confusion, or marked weakness. These signs deserve attention whether or not a fever is present at that moment.

Ask which symptoms require same-day review, whether dengue testing is appropriate, how to prevent mosquito bites at home, and which medicines are safe while dengue is being considered.
