There were 60 more pregnant women in the 50 states and the District of Columbia with laboratory evidence of Zika infection for the week ending Sept. 8, according to the Centers for Disease Control and Prevention.
That is the largest weekly increase yet among that population, and it brings the total number of Zika-infected pregnant women to 731 in the 50 states and D.C. so far in 2016. The U.S. territories reported 76 new cases for the week ending Sept. 8, for a territorial total of 1,156 and a combined U.S. total of 1,887 pregnant women with Zika virus, the CDC reported Sept. 15.
For the second week in a row, a liveborn infant with Zika-related birth defects was born in the 50 states/D.C. The total is now 19 for the year: 18 in the states/D.C. and 1 in the territories. There were no new pregnancy losses with Zika-related birth defects, so the number holds at six for the year: five in the states/D.C. and one in the territories, the CDC said.
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.
The figures for states, territories, and D.C. reflect reporting to the U.S. Zika Pregnancy Registry; data for Puerto Rico are reported to the U.S. Zika Active Pregnancy Surveillance System.
