WHO published interim guidelines on the prevention of sexual transmission of Zika virus in September 2016 (1), based on a limited amount of evidence under an emergency process during a public health emergency of international concern. The body of evidence has grown considerably since then and WHO experts concluded, at a meeting in March 2017, that the guidelines should be developed under the formal WHO guideline process (2). These guidelines contain updated recommendations on the prevention of sexual transmission of Zika virus, based on the best available evidence as of June 2018.

Updated 6 September 2016. This guidance has been developed to provide advice on the prevention of potential sexual transmission of Zika virus. The primary transmission route of Zika virus is via the Aedes mosquito. However, sexual transmission of Zika virus may also be possible, with limited evidence recorded in a few cases. This is of concern due to an association between Zika virus infection and potential complications, including microcephaly and Guillain-Barré syndrome.

This Rapid Advice Guideline updates the Interim Guidance on the “Assessment of infants with microcephaly in the context of Zika virus” published in February 2016 (WHO/ZIKV/MOC/16.3). The recommendations provides guidance on the screening, clinical assessment, neuroimaging, laboratory investigation and follow-up of children born to women living in areas of Zika virus transmission. The Guideline summarises the evidence base and rationale in support of the recommendations and expands the scope to address complications beyond microcephaly and what is now referred to as the congenital Zika virus syndrom

Updated 22 august 2016. This document aims to provide interim guidance on the case definition of GBS and strategies to manage the syndrome, in the context of Zika virus and its potential association with GBS. This document is intended to inform the development of local clinical protocols and health policies related to the care of patients with GB
