Answer

Until recently, the mosquito was the only known vector for Zika virus transmission. As the infection spreads, new possible routes of transmission facilitating human-to-human spread of the virus without an intermediate vector have been discovered. The CDC has issued interim guidelines advising sexual abstinence or regular use of condoms to prevent the spread of Zika virus to sexual partners, especially during pregnancy. [39]

On July 6, 2018, FDA issued guidance to all blood centers in all states and US territories to screen donated whole blood and blood components with blood screening nucleic acid test approved by FDA. An FDA-approved pathogen-reduction device can considered to be used for plasma and apheresis platelet donations. [40]
