Causes of dengue virus
Dengue virus is caused by infection with 1 of 4 related viruses known as Dengue-1, Dengue-2, Dengue-3, and Dengue-4. Infection from one type gives you lifelong immunity to that particular dengue virus. However, the condition does not offer immunity to the other three types, so it is possible to contract the dengue virus again. A person who has had the dengue virus is at increased risk of experiencing more severe this symptoms if they get infected again.

Australia in dengue virus
Cases of dengue virus occur in northern Queensland from when travelers who have been infected out of the country return & introduce the virus to the local mosquito population. In this situation, it isn’t as common as in other tropical regions.
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.
Avoid mosquito bites and avoid the dengue virus in commonly affected areas.
Protect yourself against mosquito bites to avoid the dengue virus (and other mosquito-borne diseases) in dengue-affected areas. Suggestions include:
- 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.)
- Apply insect repellent first thing in the early morning because dengue mosquitoes bite during the day, both outdoors and inside homes and other areas.
- Apply the product, such as permethrin, to your clothes or your bedding.
- They are using it all over the bed net (mosquito net).
- Stay in air-condition accommodation with flyscreens on the windows.
