"There is no longer any doubt that Zika causes microcephaly," said C.D.C. director Dr. Thomas R. Frieden. He said "mounting evidence from many studies," pointed to "an unprecedented association."

"Never before in history has there been a situation where a bite from a mosquito can result in a devastating malformation," Frieden said.
