The Centers for Disease Control and Prevention updated the way it reports Zika-affected pregnancies. The goal: to get a better grip on the true risk of having a birth defect after a Zika infection.
The CDC said the new numbers show 279 women who tested positive for the virus. This includes 157 women in the 50 states and Washington, D.C, plus 122 in Puerto Rico, the U.S. Virgin Islands and other U.S. territories.
