A sobering report on the impact of Zika in children exposed to the virus in the womb.

A Centers for Disease Control and Prevention study finds that about 1 in 7 babies exposed to Zika during pregnancy appear to have significant, ongoing health issues.

The study involved 1,450 babies born in Puerto Rico and U.S. territories, who had been exposed to the virus, and who were 1 year old by February 2018. Six percent were born with birth defects, and 14 percent developed problems that could be blamed on the virus by the time they turned one year old.

Director of the CDC Dr Robert Redfield says, "Zika is still a risk, especially for pregnant women and their babies."

Pregnant women and couples trying to conceive should continue to protect themselves while living or visiting places where Zika is being transmitted. The virus is primarily spread by mosquitoes, but can also be spread sexually. The government issued new guidelines Tuesday. CDC now recommends men wait three months after exposure to Zika before trying to conceive. The CDC had previously recommended waiting six months. But the latest science suggests the virus doesn't remain infectious in semen as long as previously thought. Women are still be urged to avoid traveling to areas were Zika is spreading.
