Sexual Transmission of Zika Virus – a literature review

Miranda Sherley , Chong-Wei Ong


Zika virus is an emerging health threat worldwide. A member of the yellow fever virus family, it is primarily spread by mosquitoes of the Aedes (Stegomyia) genus.(1) Unusually for a mosquito-borne virus, sexual spread has also been reported; with cases of male-to-female, female-to-male and male-to-male sexual transmission all now published in the scientific literature, in both symptomatic and asymptomatic infection.(2-19) Female-to-female sexual transmission has not yet been reported but is biologically plausible. The extent of the impact of sexual transmission on the spread of Zika virus around the world is not well characterised but has particular relevance to travellers to and from non-endemic regions, and assisted reproduction services.
