Scientists get clearer picture of Zika virus and pregnant women. Registered Nurse Ali Gorman reports during Action News at 5 p.m. on June 9, 2017. (WPVI)

Scientists have struggled with estimating the risk of the Zika virus to pregnant women in the past, but now they have a clearer picture.

They also found the risk for birth defects is greatest when a woman is infected during the first trimester.

And even if a woman has no symptoms of the virus, her baby can still be affected.

Scientists are still working on a vaccine.

In the meantime, health officials urge women who are pregnant to avoid Zika-affected areas.

Their male partners also need to take precautions.
