List of Zika virus affected countries

The risk assessment for Zika virus transmission uses current and historical information from a range of sources to make an assessment of current transmission levels of Zika virus. This is subject to change, and information checked today may not be the same tomorrow, or in coming months. We recommend regular review of the country list.

*Widespread transmission: Countries/territories/areas with >10 cases vectorborne transmission within the last three months

#Sporadic transmission: Countries/territories/areas with 1-9 cases vectorborne transmission within last three months

+Historical transmission: Countries/territories/areas with no reported cases within the last 3 months, but evidence of vectorborne transmission since 2007

Additional factors considered in determining risk category include:

  • Information on surveillance and response measures (outbreak or vector control, community engagement) in the affected country
  • Whether nearby countries are experiencing widespread transmission
  • Ongoing listing as a Zika virus affected country by a major public health agency or the World Health Organization

For countries with evidence of transmission prior to 2007, refer to the WHO timeline.

The mosquitoes that spread Zika virus usually do no live at elevations above 2,000metres. The risk of mosquito borne transmission in such areas of high elevation within a country is minimal.

Post exposure advice

Avoid pregnancy for at least 8 weeks following return.

Pregnant women should avoid unprotected sex with a partner (male or female) who has been to a high or moderate risk country for the duration of the pregnancy.

If male partner has a confirmed Zika infection (clinical or laboratory), avoid pregnancy and unprotected sex for at least 6 months from the time of diagnosis.

Males and females should avoid unprotected sex for at least 8 weeks following return.*

Travellers returning to areas of Queensland with suitable mosquitoes to transmit Zika should avoid mosquito bites for 4 weeks after return.

Please refer to "High Risk"

Advice based on Individual Risk assessment.

Elements from high and moderate risk categories may apply.

For further information, please refer to Zika – the basics (refer to Zika Virus Factsheet - the Basics)

* If prevention of sexual transmission is not important (partner not at risk of pregnancy, or does not reside in areas of Queensland with the vector) - based on the outcomes of a post-travel individual risk assessment, this measure may not be required.
