"The United States is likely to see outbreaks of the Zika virus, with perhaps dozens or scores of people affected, said Dr. Anthony Fauci, director of the U.S. National Institute of Allergy and Infectious Diseases, on Sunday.

The United States has seen more than 350 cases of people who were infected abroad and then returned to the country but has yet to confirm a case where someone was infected within its borders. That is likely to change, said Fauci.

"It is likely we will have what is called a local outbreak," he said on Fox News Sunday with Chris Wallace.

The Zika outbreak was first detected in Brazil last year and is spreading through the Americas. It has been linked to thousands of cases of microcephaly, a typically rare birth defect marked by unusually small head size which often indicates poor brain development. The World Health Organization declared a global health emergency in February."
