Symptoms
Zika viral illness manifests similar symptoms to dengue and chikungunya although symptoms are usually milder.
At the time of writing, Zika virus had been linked to severe medical conditions when infections are passed from pregnant women to their unborn babies. Zika virus can be transmitted in blood and via sexual contact.
The current recommendation is that pregnancy should be deferred for at least six months after returning from an affected area in all cases, even without being unwell. Pregnancy should be deferred for up to six months for male partners who have been infected.
