Additional precautions: Chikungunya is spread by mosquito bites, so it is important to use insect repellent, wear long sleeves, and reduce exposure to mosquitoes, especially during the daytime. Vaccination may be considered for some travellers based on destination, outbreak activity, and personal risk.
