Dengue

Dengue is a viral infection spread by mosquitoes. It's widespread in many parts of the world.

In most people the infection is mild and passes in about a week without causing any lasting problems. But in rare cases it can be very serious and potentially life threatening.

There's no specific treatment or widely available vaccine for dengue, so it's important to try to avoid being bitten by mosquitoes when visiting an area where the infection is found.
