The Department of Health is warning Pilbara and Kimberley residents to take additional precautions to avoid mosquito bites following continued detections of Murray Valley encephalitis (MVE) virus.
While no human cases of MVE have been reported this year, evidence of the virus has now been detected from the sentinel chicken surveillance program coordinated by the Department of Health, PathWest and local governments, to provide early warning of virus activity.
Department of Health Medical Entomologist, Dr Peter Neville said MVE was carried by mosquitoes and had no specific cures or vaccines.
“The only effective protection against the virus is to take precautions to avoid being bitten by mosquitoes,” he said.
“While the risk of being infected and becoming unwell is low, the illness caused by the virus can be severe and potentially fatal.”
Initial symptoms of MVE include fever, drowsiness, headache, stiff neck, nausea and dizziness. People experiencing these symptoms should seek medical advice immediately. In severe cases, people may experience fits, lapse into a coma, be left with permanent brain damage or die.
In young children, fever might be the only early sign. Parents should seek medical advice if concerned; particularly if their child experiences drowsiness, floppiness, irritability, poor feeding, or general distress.
Residents of Pilbara and Kimberley are advised to take the following steps to minimise exposure to mosquitoes:
- avoid outdoor exposure around dawn and early evening;
- wear protective (long, loose-fitting, light-coloured) clothing when outdoors;
- apply an effective personal repellent containing diethyltoluamide (DEET) or picaridin to exposed skin or clothing and always follow label instructions;
- remove water-holding containers from around the home and garden to ensure mosquitoes do not breed in your backyard;
- use mosquito coils and mosquito lanterns and applying barrier sprays containing bifenthrin in patio and outdoor areas around houses;
- ensure insect screens are installed and in good condition on houses and caravans;
- use mosquito nets and mosquito-proof tents if sleeping outside; and
- ensure infants and children are adequately protected against mosquito bites, preferably with suitable clothing, bed nets or other forms of insect screening.
