Bethesda, MD – Zika virus is capable of replicating and spreading infectious particles within the outermost cells lining the vaginal tract, according to new research. The findings provide the first molecular-level insights into how the virus can move from person to person through sexual contact.
While Zika is primarily spread by mosquitoes, researchers have been aware of its potential for sexual transmission based on cases in which people became infected after having sex with a partner who had visited a Zika-affected area. Previous studies have also found Zika particles present in semen and vaginal fluid from infected individuals.
