At this time there is no vaccine for Dengue / Hemorrhagic Fever; so preventing infection is your only line of defense against contracting the virus.

The best way to avoid infection is by avoiding mosquito bites.


  • The mosquitos that carry the Dengue are active mostly during daylight hours.
    Visitors to St John, the Virgin Islands and the islands throughout the Caribbean can reduce the chances of being bitten and contracting the virus by following these guidelines:
  • Make sure that screens are secure and/or use air conditioning in your home. The use of mosquito bed nets is another line of defense.
  • Empty standing water in and around your home or villa as these are prime breeding grounds for mosquitos.
  • Wear long sleeve shirts and long pants for added protection.
  • Use insect repellants that contain DEET, picaridin, IR3535, oil of lemon and eucalyptus and/or para-menthane-diol bug sprays.
  • If using with sunscreen – apply the sunscreen first and bug spray last.
  • Always follow the manufacturer’s directions when applying insect repellants.
