• As both chikungunya and dengue are transmitted through the bite of infected Aedes aegypti mosquito, protection from mosquito bites is the only prevention.
• Use mosquito repellent with DEET on the skin, and wear long sleeve pants and shirts when outside during times that mosquitoes bite, whether in the Cayman Islands or on travels.
