Zika is a viral infection that is transmitted to humans by the same type of mosquitoes that carry dengue fever. There is currently no vaccine or treatment, but fortunately for most people the infection is mild and usually resolves itself within a week.

However, Zika can pass from a pregnant woman to her baby and is linked to birth defects such as microcephaly, which results in an abnormally small brain and skull. For this reason, pregnant women or those planning a pregnancy are at higher risk and are advised to avoid traveling to Zika-affected countries.

In recent years a Zika epidemic has developed across much of the tropics, starting in Brazil before spreading into the Americas and Southeast Asia. The virus has affected many of the world’s most popular travel destinations, particularly for couples planning honeymoons and babymoons.

Be sure to plan ahead, choose your destination carefully and take sensible precautions to avoid mosquito bites.
