The mosquito-borne Zika virus is an epidemic in Central and Latin America, and the World Health Organization has declared it a global health emergency.
Zika causes mild illness or no symptoms in most people but is believed to be linked to a birth defect that causes babies to be born with unusually small heads.
Australian Stock Exchange-listed Starpharma Holdings and Ansell combined to produce the Dual Protect condoms, which provide protection via the physical barrier and a lubricant that contains an antiviral agent that counteracts viruses that cause sexually transmitted infections.

The CDC also recommends that all travelers use insect repellent while in outbreak areas and continue to use it for three weeks after travel in case they might be infected but not feel sick.
