Cases of Zika in Pregnant Women Triples in US
The number of pregnant women in the continental United States who are infected with the Zika virus has more than tripled, from 48 to 157, federal health officials said Friday. Another 122 pregnant women in Puerto Rico have tested positive for the virus. Officials from the Centers for Disease Control and Prevention said that the new numbers primarily reflect a new case definition as opposed to a surge in infections. The CDC now includes all women who have either tested positive for the Zika virus or are likely positive based on antibodies. Antibodies tests are not as reliable since they can result in false positives for people who have had dengue virus or yellow fever. Dr. Margaret Honein, chief of the CDC’s birth defects unit, said that the agency is aware of “less than a dozen” babies or fetuses who have microcephaly or a range of other neurological birth defects linked to Zika.
