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 2,000 metres. The risk of mosquito borne transmission in such areas of high elevation within a country is minimal.

Risk Category High Risk Moderate Risk Low Risk
* 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. Some couples may choose to abstain for shorter or longer periods depending on this individual risk assessment and risk tolerance. ^Serological tests may be used to exclude infection in some circumstances
Pre - Travel advice for women who are pregnant or planning pregnancy Defer non-essential travel or defer pregnancy Consider deferring travel or defer pregnancy, based on individual risk assessment with doctor. Advice based on Individual risk assessment. Deferring travel or pregnancy is usually not necessary.

Post exposure advice

Pregnant women should avoid unprotected sex while travelling in a Zika virus affected country. Avoid unprotected sex for the duration of pregnancy or for 6 months (whichever is longer) with a male partner who has travelled to a ‘Zika virus affected’ country. Pregnant women should avoid unprotected sex for 8 weeks with a female partner who has travelled to a ‘Zika virus affected’ country.

Women should avoid pregnancy while travelling in a high or moderate risk ‘Zika virus affected’ country and avoid pregnancy for at least 8 weeks after the last day of travel or for 8 weeks after diagnosis. Advice relating to a partner who has travelled also applies.

Men with a pregnant partner should avoid unprotected sex for the duration of the pregnancy or for 6 months after the last day in a high or moderate risk ‘Zika virus affected’ country or 6 months after diagnosis, whichever is longer.

Men with a partner who is planning pregnancy or at risk of pregnancy should avoid pregnancy for at least 6 months after the date of return from a high or moderate risk ‘Zika virus affected’ country or 6 months from time of diagnosis of infection.

Anyone who is planning a pregnancy should seek advice about the possibility of testing to exclude infection, particularly if there are concerns about the consequences of delaying pregnancy for the recommended time periods.

To minimise the risk of sexual transmission for all other men and women:

  • If a female partner has travelled or been potentially exposed, avoid unprotected sex for at least 8 weeks after the last day in a high or moderate risk Zika virus affected’ country or for 8 weeks after diagnosis.
  • If a male partner has travelled or been potentially exposed, avoid unprotected sex for at least 6 months after the last day in a high or moderate risk Zika virus affected’ country if no symptoms appear, or 6 months from time of diagnosis of infection.*

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

As for "High Risk"

Advice based on Individual Risk assessment.

Elements from high and moderate risk categories may apply.
