Zika virus is endemic in several parts of the world. February 1, 2016 Zika virus 
was declared a public health emergency by the WHO. This declaration is mainly 
due to a convincing association between Zika virus infection during pregnancy 
and birth defects, like microcephaly, among some of the newborns. Imported cases 
of Zika virus infection to North America, Europe and Denmark have been 
described. The infection in itself is mild and self-limiting. The available 
diagnostic methods are under development, validation and evaluation. In Denmark, 
some promising diagnostics are available at Statens Serum Institut.
