In the wake of a tragic death from Murray Valley encephalitis (MVE) in Western Australia, the community is being urged to take extra precautions against mosquito bites. This rare but potentially fatal illness is a stark reminder of the dangers lurking in the region's mosquito-prone environment.
The recent fatality highlights the importance of being vigilant, especially during the wet season and the period immediately after it, which are known to be high-risk times for mosquito-borne virus activity. With no vaccine available, prevention is key, and it starts with avoiding mosquito bites.
The symptoms of MVE can be severe and include severe headache, difficulty speaking or confused speech, fever, drowsiness, neck stiffness, nausea, and dizziness. In more severe cases, individuals may experience seizures, fall into a coma, suffer permanent brain damage, or even die. Young children may only show fever as an early sign of infection, so parents and carers should be especially alert and seek medical advice promptly if they have any concerns.
To protect against mosquitoes, the Department of Health recommends several measures. Firstly, cover up by wearing long, loose-fitting, light-coloured clothing and ensuring that children are dressed appropriately, including protecting their feet. Insect screens should be installed and maintained on houses and caravans, and mosquito nets and mosquito-proof tents should be used when sleeping outside.
Secondly, repel mosquitoes by applying an effective personal mosquito repellent containing diethyltoluamide (DEET), picaridin, or Oil of Lemon Eucalyptus (PMD) to all exposed skin, following the label instructions. It's crucial not to confuse Oil of Lemon Eucalyptus with eucalyptus oil or other botanicals that may not provide sufficient protection.
Lastly, clean up by keeping grass and other vegetation short to reduce mosquito breeding grounds, and empty or remove any water-holding containers around your home.
The Department of Health's surveillance programs continue to detect MVE activity in the Kimberley and Pilbara regions, emphasizing the ongoing risk in northern WA. By taking these preventive measures, the community can significantly reduce the chances of contracting MVE and contribute to a safer, healthier environment.
In conclusion, the recent MVE fatality serves as a stark reminder of the importance of mosquito bite prevention in WA. By being vigilant, taking proactive measures, and staying informed, the community can protect itself from this rare but serious illness and ensure a healthier, safer future.
