Victorians are being reminded to take steps to protect themselves against mosquito-borne diseases this summer, with recent wet and humid weather creating ideal conditions for mosquito breeding.

Ross River virus and Barmah Forest virus infections increase during the summer period across Victoria, and both are spread by mosquitoes. Symptoms include fever, chills and joint pain. While most people will get better within a few weeks, for some the recovery can take months.

Japanese encephalitis (JEV), Murray Valley encephalitis and West Nile virus/Kunjin disease are rare in Victoria but have the potential to cause severe disease. A vaccine is available for Japanese encephalitis for Victorians who meet eligibility criteria.

Bass Coast is not one of the areas of concern for JEV, but residents and visitors are advised to reduce the risk of being bitten by mosquitoes, with numerous cases of Ross River Virus detected in and around Phillip Island in recent years.

In 2021, there were 15 reported cases, in San Remo and across Phillip Island, including Cowes, Cape Woolamai, Surf Beach, Wimbledon Heights and a property along Harbison Road.

Previously, the shire said six of the seven mozzie hot spots in Bass Coast are found on Phillip Island: the Rhyll and Newhaven swamps, Fisher's wetland near Churchill Island, Rhyll foreshore, Silverleaves, the Gun Club south of Rhyll, as well as the mouth of the Powlett River at Kilcunda.

Mosquitoes can fly several kilometres if the wind conditions are right.

Ulcer

Melburnians, particularly those living in or visiting coastal areas around the bay and Bellarine and Mornington peninsulas, should also be mindful of Buruli ulcer. Symptoms of infection can take months to develop and may include persistent spots that look like insect bites, ulcers, painful lumps and lasting redness. 

The disease has been linked to possums and the main pathway of transmission to humans is via mosquito bites, so take precautions to prevent mosquito bites and avoid contact with wildlife, particularly animals showing signs of a sore or ulcer.

Simple steps you can take to keep yourself and your family safe from mosquito bites include:

• Wearing long, loose-fitting and light-coloured clothing
• Applying insect repellents containing picaridin or DEET on exposed skin
• Avoiding mosquitoes when they are most active, particularly around dawn and dusk
• Making sure your accommodation is fitted with mosquito screens or nets

If camping or caravanning, keep doors and tent flaps closed to stop mosquitos getting in, ensure mosquito screens or nets are intact, and try to avoid camping near wetland habitats where mosquitos are likely breeding.
