A pregnant woman has been diagnosed with the Zika virus in Spain.
This is the first such case in Europe.
The health ministry said the woman had recently returned from Colombia, where it is believed she was infected.
Zika, which is spreading through the Americas, has been linked to babies being born with underdeveloped brains.
The World Health Organization (WHO) has declared the microcephaly condition, linked to the mosquito-borne virus, a global public health emergency.
On Thursday, the WHO also advised countries not to accept blood donations from people who had travelled to Zika-affected regions.
The link between Zika infection and microcephaly has not been confirmed and the risks at different stages of pregnancy are unknown.
The WHO has predicted that at least four million people could be infected with Zika in the Americas in 2016.
The agency expressed belief that most victims would not develop symptoms, stressing that the infection had been linked to brain defects in babies.
