The first new case of a live-born infant with Zika virus–related birth defects in almost a month was reported during the week ending Sept. 1, bringing the U.S. total to 18 so far, according to the Centers for Disease Control and Prevention.
The infant was born in one of the 50 states or the District of Columbia and is the first case of a Zika-related birth defect reported since the week ending Aug. 4. The CDC is not reporting state- or territorial-level data to protect the privacy of affected women and children. There were no new Zika-related pregnancy losses for the week of Sept. 1, so the total remains at six for the states, D.C., and the territories, the CDC reported Sept. 8.
The number of pregnant women with any laboratory evidence of Zika infection increased by 156 during the week ending Sept. 1: 47 new cases in the states/D.C. and 109 new cases in the territories. The total number of pregnant women with Zika for 2016 is now 1,751, the CDC said.
For 2015-2016, there have been 18,833 cases reported in the entire U.S. population: 2,964 in the states/D.C. (all but 44 were travel associated) and 15,869 in the territories. All but 60 cases in the territories were locally acquired, and 98% have occurred in Puerto Rico, the CDC also reported Sept. 8.
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.
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.
