    About Dengue (Breakbone fever)

    Dengue is a viral infection transmitted by the Aedes mosquito. The disease causes high fever and severe muscle and joint pain. With repeated infection, severe (hemorrhagic) dengue can occur.

    How is it transmitted?

    The virus is transmitted by Aedes aegypti and Aedes albopictus mosquitoes, which are most active during the day. These mosquitoes are mainly found in and around built-up areas.
