This article contains important information to help all Victorian early childhood education and care (ECEC) services minimise the spread of mosquito-borne diseases such as Murray Valley encephalitis virus and Japanese encephalitis virus infections.

Warm and wet weather can result in greater numbers of mosquitoes and increased risk of illnesses from mosquito bites.

The best protection against mosquito-borne illness is to avoid mosquito bites.

Please share this information with your staff and use the template newsletter text with parents and carers.

On Monday 30 January 2023, centre-based ECECs in high-risk areas received an email with specific actions to assist them in protecting staff and children against mosquito-borne diseases.

This advice contains important information for ECEC services across the state.

How to protect against mosquito-borne diseases

Mosquitoes are generally more active around dusk and dawn but can also bite during the day. The peak mosquito period is from October to March.

Consistent with community health advice, there are some simple steps that families and staff can take to help protect against mosquito bites:

  • use mosquito repellent that contains picaridin or DEET on exposed skin if outdoors when mosquitoes are observed. It is important to review the instructions on repellent containers to ensure it is suitable for younger children. In some instances, repellent can be applied to clothing and should be avoided on young children’s hands, eyes and mouth
  • wear long, loose-fitting clothing if mosquitoes are around and cover exposed skin as much as possible
  • limiting outdoor activity when mosquitos are active.

Services can also reduce the risk of mosquito bites by:

  • preventing mosquitoes from getting inside, for example by closing windows and doors or using fly screens, particularly at times when mosquitoes are active. It is recommended you use air purifiers where available to reduce the risk of airborne illnesses
  • preventing mosquitoes from breeding around the service, for example by:
    • cutting back long grass and shrubs where mosquitoes can rest, especially around outdoor areas where people gather
    • removing or emptying containers capable of holding water (including rubbish bins, pots and bird baths)
    • checking and maintaining rainwater tanks and water storage vessels.

Staff or families with any health concerns should see their doctor or phone Nurse-on-call: 1300 606 024 (available 24 hours).

Excursions to high-risk areas

As at Sunday 29 January 2023, the following local government areas (LGAs) are considered high-risk for mosquito-borne disease: Benalla, Buloke, Campaspe, Gannawarra, Greater Bendigo, Greater Shepparton, Hindmarsh, Horsham, Indigo, Loddon, Mildura, Moira, Northern Grampians Shire, Strathbogie, Swan Hill, Wangaratta, West Wimmera, Wodonga and Yarriambiack.

If planning an excursion in a high-risk LGA, your service is advised to:

  • actively promote insect repellent application for staff and children (if age-appropriate – please read the label)
  • take preventative measures if mosquitoes are noticeably impacting children and staff (for example, pause activities to apply repellent and put on long loose-fitting clothing)
  • where possible, move activities indoors or into protected areas if mosquitoes are prevalent.
