Health officials in Denmark said Wednesday a resident who had traveled to South and Central American has tested positive for the Zika virus.
According to the World Health Organization, the mosquito-borne virus could be linked to 4,000 suspected cases of microcephaly in Brazil, a condition that results in abnormally small heads in newborns and can affect brain development.
There is no treatment or cure for Zika virus infections, and an outbreak in Brazil and at least 20 other countries and territories in the Americas has prompted public health warnings.
Authorities in El Salvador and Colombia have recommended women postpone getting pregnant. In Brazil, 200,000 troops are traveling to homes to distribute pamphlets with advice on mosquito eradication.
