Locals and travellers in the Kimberley region of northern Western Australia are warned to beware of mosquitoes after a deadly virus was detected.
WA Health said Murray Valley encephalitis (MVE) had been found in mosquitoes and sentinel chickens for the first time this year.
Mosquitoes have also been pinpointed as the cause of a spike in Ross River virus cases in the same region.
WA Health managing scientist Dr Andrew Jardine said recent activity followed significant rainfall in the region, which created ideal conditions for mosquitoes.
“Ross River and Murray Valley encephalitis viruses are only spread by mosquitoes – so the message is simple: protect yourself from being bitten,” Jardine said.
“Many people are bitten when fishing or camping – make sure you pack an effective repellent and follow all the advice to avoid mosquito bites.
“While the risk of getting infected and becoming sick is low, the illness caused by the virus can be severe in some cases.”
People are advised to take the following steps to avoid mosquito bites.
- Avoid being outdoors at dawn and early evening when mosquitoes are most active.
- Wear long, loose-fitting, light-coloured clothing.
- Dress babies and children in suitable clothing, including socks/shoes, and use bed/pram netting.
- Apply an effective personal mosquito repellent containing diethyltoluamide (DEET), picaridin or oil of lemon eucalyptus (also known as PMD) evenly to all areas of exposed skin and always follow the label instructions.
- Ensure insect screens are installed and in good condition on houses and caravans.
- Use mosquito nets and mosquito-proof tents if sleeping outside.
- Keep grass and other vegetation short to help prevent mosquitoes around your home.
MVE is a serious and potentially fatal disease.
Symptoms include fever, drowsiness, headache, stiff neck, nausea, and dizziness. In young children, fever may be the only early sign of infection.
It looks like tinned spaghetti but it kills 2500 people a year
Any person experiencing these symptoms should seek urgent medical advice.
The Kimberleys also experienced a slew of MVE cases last year, including two in children, one of which was fatal.
