United States up to 855 cases of Zika in pregnant women



There was one live-born infant with Zika virus–related birth defects and 77 new cases of Zika among pregnant women reported during the week ending July 21, 2016, in the United States, but no additional Zika-related pregnancy losses, according to the Centers for Disease Control and Prevention.

The new cases bring the totals to 13 infants born with birth defects and 855 pregnant women with any laboratory evidence of Zika virus infection. All of the infants with birth defects so far were born in the 50 states and the District of Columbia, which is where six of the seven Zika-related pregnancy losses occurred. There has been only one pregnancy loss in the U.S. territories, but the territories account for almost half (422) of the 855 pregnant women with Zika infection. Of the 77 new infections in pregnant women for the week, 44 occurred in the territories and 33 were in the states, the CDC reported July 28.

The figures for states, territories, and the District of Columbia reflect reporting to the U.S. Zika Pregnancy Registry; data for Puerto Rico are reported to the U.S. Zika Active Pregnancy Surveillance System.

Zika-related birth defects recorded by the CDC could include microcephaly, calcium deposits in the brain indicating possible brain damage, excess fluid in the brain cavities and surrounding the brain, absent or poorly formed brain structures, abnormal eye development, or other problems resulting from brain damage that affect nerves, muscles, and bones. The pregnancy losses encompass any miscarriage, stillbirth, and termination with evidence of birth defects.
