Zika virus is a flavivirus transmitted primarily by Aedes species mosquitoes. Increasing evidence links Zika virus infection during pregnancy to adverse pregnancy and birth outcomes, including pregnancy loss, intrauterine growth restriction, eye defects, congenital brain abnormalities, and other fetal abnormalities. The virus has also been determined to be sexually transmitted. Because of the potential risks associated with Zika virus infection during pregnancy, CDC has recommended that health care providers discuss prevention of unintended pregnancy with women and couples who reside in areas of active Zika virus transmission and do not want to become pregnant. However, limitations in access to contraception in some of these areas might affect the ability to prevent an unintended pregnancy. As of March 16, 2016, the highest number of Zika virus disease cases in the United States and U.S. territories were reported from Puerto Rico. The number of cases will likely rise with increasing mosquito activity in affected areas, resulting in increased risk for transmission to pregnant women. High rates of unintended and adolescent pregnancies in Puerto Rico suggest that, in the context of this outbreak, access to contraception might need to be improved. CDC estimates that 138,000 women of reproductive age (aged 15-44 years) in Puerto Rico do not desire pregnancy and are not using one of the most effective or moderately effective contraceptive methods, and therefore might experience an unintended pregnancy. CDC and other federal and local partners are seeking to expand access to contraception for these persons. Such efforts have the potential to increase contraceptive access and use, reduce unintended pregnancies, and lead to fewer adverse pregnancy and birth outcomes associated with Zika virus infection during pregnancy. The assessment of challenges and resources related to contraceptive access in Puerto Rico might be a useful model for other areas with active transmission of Zika virus.
寨卡病毒是一种黄病毒,主要通过伊蚊属的蚊子传播。越来越多的证据表明,孕妇感染寨卡病毒与不良妊娠和分娩结局有关,包括妊娠丢失、宫内生长受限、眼部缺陷、先天性脑异常和其他胎儿异常。该病毒也已被确定可通过性传播。由于孕妇感染寨卡病毒可能带来的风险,美国疾病预防控制中心建议,在寨卡病毒传播活跃地区居住且不想怀孕的卫生保健提供者应与妇女和夫妇讨论预防意外怀孕的问题。然而,在这些地区,一些人可能因获取避孕措施的机会有限而无法避免意外怀孕。截至 2016 年 3 月 16 日,美国和美国领土报告的寨卡病毒病病例数最多的是波多黎各。随着受影响地区蚊子活动的增加,病例数可能会上升,从而增加孕妇感染的风险。波多黎各意外怀孕和青少年怀孕的比例较高,这表明在疫情背景下,需要改善获取避孕措施的机会。美国疾病预防控制中心估计,波多黎各有 13.8 万名育龄妇女(年龄在 15-44 岁之间)不希望怀孕,且未使用最有效或中度有效的避孕方法之一,因此可能会意外怀孕。美国疾病预防控制中心和其他联邦及地方合作伙伴正在努力扩大这些人的避孕措施获取途径。这些努力有可能增加避孕措施的获取和使用,减少意外怀孕,并降低与孕妇感染寨卡病毒相关的不良妊娠和分娩结局。评估波多黎各获取避孕措施的挑战和资源,可能是其他寨卡病毒传播活跃地区的一个有用模式。
