How the dengue virus is viral.

Dengue virus is not transmitted (spread) from person to person, and only infected mosquitoes transmit the dengue virus. It is thought that a mosquito contracts the virus when it bites an infected person, and the mosquito is then infective for the rest of its lifetime and can spread the virus every time it bites someone.

At least three kinds of mosquitoes in Australia are suspected of being dengue carriers. They are Aedes aegypti, Aedes scutellaris Aedes katherinensis. These mosquitoes are found in northern Queensland, and the Northern Territory, & northern Western Australia & are not located these mosquitos in Victoria.

  • Wear socks, long pants, and long-sleeved shirts—loose-fitting clothes weare make it harder for mosquitoes to bite through your clothes.
  • Wear mosquito repellent that contains active constituents DEET (N, N-Diethyl-m-toluamide) or picaridin. Reapply regularly and follow directions for safe use on the label. (For young children, it can be safer to spread insect repellent on their clothes rather than their skin.)
