What is dengue?

An infection caused by the dengue virus, carried by mosquitoes. Most people have mild or no illness, but it can become severe.

Signs
High fever, bad headache, pain behind the eyes, aching muscles and joints, feeling sick, vomiting, swollen glands and rash. Usually lasts two to seven days.
How it spreads
Through the bite of an infected Aedes mosquito, which bites mainly in the daytime. Rarely, through blood transfusions, organ donation, or from mother to baby.
How to protect yourself
Cover up, use nets, window screens and repellent. Empty, clean and cover anything holding water weekly. A vaccine is licensed in some countries for children aged 6 to 16 in high-risk areas.
Get medical help
Get help immediately, often just after the fever drops, for bad stomach pain, repeated vomiting, fast breathing, bleeding gums or nose, blood in vomit or poo, or cold pale skin. Use paracetamol, not ibuprofen or aspirin.

A reported case means someone reached a clinic and a form was filed, so these count reports, not everyone who was ill.
