    The explosion of cases of birth defects caused by Zika virus may be the "tip of the iceberg," experts said Sunday.

    Many cases have probably been missed because babies looked normal when they were born, NBC News reported. But hidden birth defects are almost certain to turn up as the babies grow.

    "The microcephaly and other birth defects we have been seeing could be the tip of the iceberg," Dr. Sonja Rasmussen of the CDC said at the annual meeting of the Pediatric Academic Societies in Baltimore. Brazil has confirmed 2,844 cases of Zika in pregnant women.

    But there is some good news coming out of the early observations of the yearlong epidemic in Brazil: Children are rarely infected with Zika.
