Travellers should be advised to take measures to avoid being bitten by Aedes mosquitoes. No medications or vaccines are available to prevent a person from getting sick with Zika fever. Preventive measures are recommeded by the US Centers for Disease Control and Prevention (CDC) and include the following:

	Select accommodations with well-screened windows or air-conditioning when possible. Aedes mosquitoes typically live indoors and are often found in dark, cool places such as in closets, under beds, behind curtains, and in bathrooms. A traveler should be advised to use insecticides to get rid of mosquitoes in these areas.
	Wear clothing that adequately covers the arms and legs, especially during the early morning and late afternoon.
	Apply insect repellent to both skin and clothing (e.g., permethrin). The most effective repellents contain DEET (N,N-diethylmetatoluamide).
	For long-term travelers, empty and clean or cover any standing water that can be mosquito-breeding sites in your accommodation (see also prevention by mosquito control).

Although there is no specific treatment for the disease, a doctor may be able to help treat your symptoms. Avoid getting any other mosquito bites, because if you are sick and a mosquito bites you, it can spread the disease to other people. Because of the "growing evidence of a link between Zika and microcephaly" the CDC issued a travel alert on January 15, 2016 advising pregnant women to consider postponing travel to the following countries and territories: Brazil, Colombia, El Salvador, French Guiana, Guatemala, Haiti, Honduras, Martinique, Mexico, Panama, Paraguay, Suriname, Venezuela, and the Commonwealth of Puerto Rico. The agency also suggested that women thinking about becoming pregnant should consult with their physicians before travelling. For more travel health information, see the CDC destinations section and search for the country you are planning to visit (see also figure 1).
