The World Health Organisation has advised all the nations against accepting blood donation from countries affected by Zika virus.
According to The Guardian, Spain announced Europe's first known case of the disease in a pregnant woman.
The announcement came as authorities in Brazil disclosed two cases of transmission tied to blood transfusions, adding a new dimension to efforts to limit Zika's impact.
With dozens of cases emerging in Europeans and North Americans returning from Zika-affected areas, the WHO stressed the potential link between Zika and microcephaly, which causes children to be born with abnormally small heads, and urged health authorities to take precautions.
