After the most recent heavy rainfall and warm weather, regional Victorians are being warned about the increase in mosquito numbers and the dangers of mosquito-borne diseases.
The current climate is a perfect breeding ground for the insect, which are currently in their peak season of November to April.
While no cases of mosquito-borne diseases have occurred this season, flood waters have now increased the risk of occurrence of the Ross River virus, Murray Valley encephalitis and Japanese encephalitis.
Japanese encephalitis is the most dangerous of the three, which in serious cases can cause brain swelling, sudden headaches, high fever and disorientation — and in some cases long term health complications.
Regional Victorians have been urged to follow steps whilst in high risk areas to reduce the chance of being bitten, including:
Covering up by wearing long, loose-fitting clothing — mosquitoes can bite through tight clothing
Using mosquito repellents containing Picaridin on all exposed skin
Checking the repellent label before applying to children — spraying or rubbing repellent on children’s clothes is recommended, avoiding their skin especially their hands
Limiting outdoor activity if there is a significant uptick in mosquitoes and using ‘knockdown’ fly spray, mosquito coils or plug-in repellent while sitting or eating outdoors
Removing stagnant water where mosquitoes can breed around the home or a campsite
Making sure windows are fitted with mosquito netting or screens
Residents in high-risk areas are eligible for a free Japanese encephalitis vaccine, which could be available through your local GP or community pharmacies.
Clarendon Medical Centre practice manager Andrew Love encouraged residents to follow advice.
“We haven’t had to deal with any cases recently and it is very unlikely that cases will come up in the region, even with the increase of mosquitoes,” he said.
“Following the steps should prevent any serious dangers of any mosquito-borne diseases.”
Minister for Health Mary-Anne Thomas warned mosquito numbers can pose a risk in regional parts of the state.
“Pooling water and warm weather unfortunately create ripe conditions for mosquito numbers to soar — it’s important people in flood-affected areas know how to protect themselves from disease in the coming weeks,” she said.
“There are many simple steps Victorians can take to avoid being bitten, whether that’s using mosquito repellent, covering up or limiting time outdoors, and getting the free Japanese encephalitis vaccine in high-risk areas.”
