Zika — a virus carried by Aedes mosquitoes
Most people who catch it have mild symptoms or none at all, but it is dangerous in pregnancy: the virus can harm the baby's development. It is carried by the same mosquitoes as dengue and chikungunya.
Where you come across it. Planning a trip while pregnant, news about the tiger mosquito.
There have been no locally acquired cases in Portugal. If you are pregnant, discuss any trip to a country where Zika circulates constantly with a doctor in advance, not once you are there.
