Puerto Rico has been heavily impacted by Zika virus, a mosquitoborne flavivirus that emerged in the Americas during 2015. Although most persons with Zika virus show no symptoms, the virus can cause neurologic and other complications, including fetal microcephaly. Local Zika virus transmission in Puerto Rico has been reported since December 2015. To prevent transfusion-associated transmission, local blood collection ceased in March 2016 but resumed in April 2016 after Zika virus screening of blood donations became available. Using data from screening of blood donations collected by the 2 largest blood centers in Puerto Rico during April 3-August 12, 2016, and assuming a 9.9-day duration of viremia, we estimated that 469,321 persons in Puerto Rico were infected during this period, for an estimated cumulative incidence of 12.9%. Results from blood donation screening during arboviral outbreaks can supplement routine clinical and surveillance data for improved targeting of prevention efforts.
波多黎各受到寨卡病毒的严重影响。寨卡病毒是一种通过蚊子传播的黄病毒，于2015年在美洲出现。虽然大多数感染寨卡病毒的人没有症状，但该病毒可导致神经及其他并发症，包括胎儿小头畸形。自2015年12月起，波多黎各已报告寨卡病毒的本地传播。为防止输血相关传播，2016年3月当地停止采血，但在2016年4月对献血进行寨卡病毒筛查后恢复采血。利用2016年4月3日至8月12日期间波多黎各最大的两个血液中心采集的献血筛查数据，并假设病毒血症持续时间为9.9天，我们估计在此期间波多黎各有469,321人感染，估计累积发病率为12.9%。虫媒病毒爆发期间的献血筛查结果可补充常规临床和监测数据，以更好地确定预防工作的目标。
