What is dengue?

Dengue is a disease caused by a virus spread through mosquito bites. The disease can take up to 2 weeks to develop with illness generally lasting less than a week.

Health effects from dengue include fever, headache, nausea, vomiting, rash, muscle and joint pain, and minor bleeding.

Dengue can become severe within a few hours. Severe dengue is a medical emergency, usually requiring hospitalization.

In severe cases, health effects can include hemorrhage (uncontrolled bleeding), shock (seriously low blood pressure), organ failure, and death.
