Prevention when travelling

Protect yourself against mosquito bites while travelling to reduce the risk of bringing mosquito borne diseases home with you. 

Get vaccinated before you travel. If travelling overseas, you could be at risk of exotic mosquito borne diseases.

  • You can be vaccinated against yellow fever and Japanese encephalitis.
  • Seek medical advice regarding the possible need for malaria prophylaxis.

No vaccines are available for:

  • Malaria
  • Dengue fever
  • Chikungunya virus
  • Zika virus.

Find information about travelling overseas on the Smartraveller website.


Dengue fever outbreaks generally begin in Queensland when someone is infected with dengue overseas and arrives with the virus in their blood.

Read about the dengue virus, fever and dengue mosquitoes, including information about the worldwide spread of the disease.

Most people with dengue fever arrive in Queensland after visiting countries such as Indonesia, Thailand, the Philippines, Papua New Guinea and other countries in the Asia-Pacific region. If you've been to a tropical country in the past two weeks and develop dengue fever symptoms it is important you see a doctor immediately.

When travelling overseas

There is no vaccine or medicine currently available to prevent people from getting dengue fever. Anti-malarial medication does not protect you from dengue fever. This is why it is important to avoid being bitten by mosquitoes when travelling in tropical areas. The best way to do this is:

  • Choosing screened or air-conditioned holiday accommodation, especially in tropical areas. If camping, sleep under a mosquito net and zip up tents whenever possible.
  • Wearing a good repellent (containing DEET or Picaridin), particularly during daylight hours when the dengue mosquito is most active.
  • Wearing long, light coloured, loose clothing to help protect yourself from bites, when possible.

For tourists visiting Queensland

If you are a tourist visiting Queensland, particularly northern Queensland, and you think you may have dengue fever symptoms please call 1800 DENGUE (1800 336 483) for advice, this is a free call.

Zika virus

As with dengue, there is no vaccine or medicine currently available to prevent people from getting ZIka virus and anti-malarial medication does not protect you from Zika virus.

Currently women who are pregnant or seeking to become pregnant should ask their doctor for advice if they are planning to travel to countries where the Zika virus is present.
