Keep limbs covered with clothes. Use repellant when possible. But don't worry about it much. Mosquito can bite any where anytime with all precautions also. They are day biters so make sure if kid enters garden or such mosquito prone area use repellant otherwise enjoy your trip and forget about it. No medicine or natural remedy will be able to prevent it as such it's a viral disease. Next year vaccine will be launched that's the only preventive measure so far.
