Fight the Bite campaign

• In Western Australia, mosquitoes can transmit Ross River virus, Barmah Forest virus, Kunjin virus and the potentially fatal Murray Valley encephalitis virus.
• There is currently no cure and no vaccine for any mosquito-borne disease acquired in WA.
• The only way to prevent infection is to avoid being bitten by mosquitoes.
• Cover Up – wear long, loose-fitting, light coloured clothing, covering as much of the body as you can.
• Repel – When outdoors and mosquitoes are present, apply insect repellent containing DEET (diethyltoluamide) or picaridin evenly to exposed skin.
• Clean Up – simple changes around your home can reduce mosquito breeding. Remove, empty or cover water-holding containers.

• Mosquitoes can bite anyone of any age - all Western Australians should take precautions to ensure they are not bitten by mosquitoes.
• Visitors to WA
• WA residents travelling within Australia and overseas
• Local governments 
• Outdoor event stakeholders
• General Practitioners and nurses
• Population Health Units

The peak mosquito season for the South West (including the Perth metropolitan area) of WA are the spring and summer months, from September to March.

The peak mosquito season for the Kimberley region, and parts of the Pilbara, coincides with the wet season and extends from January to May.

However mosquitoes breed all year round, so people need to remain vigilant.
