Three ultrasounds done in the early weeks of pregnancy in a Finnish woman living in the United States infected by Zika failed to show signs of brain damage in a fetus later diagnosed with the birth defect microcephaly, U.S. researchers said in a study published on Wednesday.
The woman was not identified but she was infected while traveling on vacation in Mexico, Guatemala and Belize in November 2015. The exact location of transmission was not known.
