Abstract and Introduction

Abstract

Infection with Zika virus is an emerging public health crisis. We observed prolonged detection of virus RNA in vaginal mucosal swab specimens and whole blood for a US traveler with acute Zika virus infection who had visited Honduras. These findings advance understanding of Zika virus infection and provide data for additional testing strategies.

Introduction

Zika virus is a rapidly emerging mosquitoborne virus.[1] In May 2015, Brazil reported autochthonous transmission of Zika virus.[2] Over the course of 1 year, Zika virus spread to >50 countries and territories throughout the Americas.[3] With the now confirmed link of Zika virus infection during pregnancy leading to fetal microcephaly [4] and reported cases transmitted by sexual contact,[5] it is vital to understand the natural history of infection. We report an acute case of Zika virus infection in a traveler returning from Honduras to the United States and results from serial specimens collected for >11 weeks. These new data might serve as a potential guide for public health policy.
