Health concerns rise as officials battle deadly virus!
- Replies 1
A silent but deadly threat has been lurking in the picturesque landscapes of northern Western Australia.
Transmitted by mosquitoes, this virus has recently claimed two lives in the Pilbara region, prompting a health alert and a significant increase in mosquito control efforts.
While the area's natural beauty remains undisturbed, the invisible dangers have become a pressing concern for residents, and the influx of tourists is expected during the peak winter season.
Murray Valley Encephalitis (MVE) is not a new resident in northern WA; it's endemic to the region.
However, the recent fatalities have brought renewed attention to the risks posed by this virus. Four cases were documented in WA in 2024 alone.
Although most people infected with MVE experience only mild symptoms, the virus can lead to severe illness in about one in 800 cases, including a brain infection that can result in lifelong complications or even death.
The Western Australia Health Department's managing scientist, Dr Jay Nicholson, has emphasised the gravity of the situation.
‘It's important to note there is actually no vaccine or specific treatments for Murray Valley Encephalitis,’
‘So the only effective protection against infection is to take precautions to avoid mosquito bites.’
This is particularly crucial for the elderly and the very young, who are at greater risk from the virus.
As the northern WA gears up for its winter tourist season, the Health Department proactively disseminates advice to residents and visitors.
They urged people to wear protective clothing, apply effective mosquito repellent, and maintain short vegetation around living spaces to deter mosquitoes.
Dr Nicholson also advised holiday-makers to inspect their caravans and camping gear to ensure safety.
‘If you've got a caravan from last year, you may have insect screens fitted — just make sure they're in good working condition,’ he said.
‘If you are camping outside, it's always a very good idea to have either mosquito nets or mosquito-proof tents available.’
The battle against mosquitoes is intensifying in the coastal town of Port Hedland, located 1,600 km north of Perth.
Environmental services manager Michael Cuvalo has reported an escalation in mosquito culling programs, with increased monitoring and a call to the community to report any surges in mosquito populations.
‘We've already escalated our programs…our ongoing monitoring of sites has increased as well,’ he said.
‘We're also definitely urging the community to notify us if they observe an increase in mosquito numbers in their areas or where they work.’
Accessing these breeding grounds can be challenging and hazardous for humans, but Port Hedland has recently acquired a game-changing tool: a drone.
This advanced technology has revolutionised the town's ability to deliver chemical treatments to vast areas, improving the efficiency of mosquito eradication efforts.
‘It's a phenomenal piece of technology,’ Mr Cuvalo commented.
‘It allows us to deliver chemical treatments to areas of between 12 and 15 hectares a day.’
‘Whereas previously that's been done on foot by hand walking through swamps … where at best and with multiple staff we would be treating maybe 4 or 5 hectares a day. So the ability to destroy mosquitoes has increased.’
The health alert extends beyond Pilbara, including the Gascoyne and Midwest regions, as officials work tirelessly to mitigate the risks of MVE.
In related news, health authorities in NSW cautioned residents to guard against mosquito bites after detecting the Japanese encephalitis (JE) virus in far-west NSW.
A sentinel chicken in Menindee yielded a positive result for JE during routine testing, with the mosquito population thriving under current weather conditions. Read more about this development here.
How do you deal with mosquitos to prevent the virus from spreading? How do you ensure living areas aren’t conducive to mosquito breeding? We’d love to hear your thoughts and opinions in the comments below.
