Zika Cases Include 320 Pregnant Women In U.S. According to CDC

Centers for Disease Control and Prevention said on Thursday that it is monitoring 320 U.S. pregnant women with laboratory evidence of Zika virus infection, up from 287 women a week earlier. However, the number of babies born in the United States with birth defects linked to Zika infection in mothers during pregnancy, or lost pregnancies linked to the virus, remained unchanged from last week's report at 7 and 5, respectively, according to a CDC registry created last month.
