Protecting against mosquito-borne diseases
Victoria’s mosquito season started this month and will extend to late April 2024. Warm and wet weather can result in greater numbers of mosquitoes and increased risk of illnesses from mosquito bites. While the overall risk is low, some mosquitoes carry diseases that make people sick.
The best protection against mosquito-borne illness is to avoid mosquito bites. Families can protect against mosquito bites by:
- covering up as much as possible with long, loose-fitting, light-coloured clothing
- applying insect repellent that contains picaridin or DEET on exposed skin when leaving home
- limiting outdoor activity if lots of mosquitoes are active.
To reduce the risk of illness linked to mosquitos, such as Buruli ulcer, promptly wash any new scratches or cuts with soap and clean water and apply a topical antiseptic and dressing.
Families with any health concerns should see their doctor or phone NURSE-ON-CALL: 1300 606 024 (available 24 hours).
Free Japanese encephalitis vaccines
Japanese encephalitis virus is spread to humans through bites from infected mosquitoes and can cause a rare but potentially serious infection of the brain.
Free Japanese encephalitis vaccines are available to protect Victorians at higher risk of the virus.
The Victorian Department of Health encourages eligible people who live or work in high-risk local government areas to get vaccinated ahead of summer, which brings an increased mosquito presence.
For more information, including what is considered a high risk area and eligibility for a free vaccine, refer to the Department of Health’s Japanese encephalitis webpage.
