About Zika virus

Zika virus is a flavivirus, closely related to dengue. Cases of Zika virus have previously been reported in Africa, southern Asia and the Pacific Islands. Beginning in 2014, Zika virus outbreaks have occurred throughout the tropical and sub-tropical areas of the western hemisphere, as far north as Mexico and Puerto Rico.
See a list of countries where Zika virus infections are currently occurring on the CDC website.
Because Zika, dengue and chikungunya viruses are transmitted by mosquitoes mostly active during daytime, it's important that all travelers visiting affected areas continue to take protective measures to prevent mosquito bites throughout the day.
Zika virus infection is symptomatic in only about one out of every five cases. When symptomatic, Zika infection usually presents as an influenza-like syndrome, often mistaken for other arboviral infections like dengue or chikungunya.
New Zealand currently has 15 mosquito species. The mosquito species (Aedes sp.) that are able to spread Zika virus are not normally found in New Zealand however they are found in many other countries around the world.
A national mosquito surveillance programme has been operating for some years at New Zealand's international points of entry (ports and airports). The ports and airports are monitored regularly throughout the year to ensure the early detection of any exotic mosquitoes.
You can find more information about mosquitoes on the Ministry of Health website and also tips on how to avoid mosquito bites while travelling.
Zika virus infection is notifiable in New Zealand as an arboviral disease.
