NSW Health is reminding people to protect themselves from mosquitoes when they are out and about during the summer holidays.

NSW Health’s Acting Director of Environmental Health, Paul Byleveld, said with more people spending time outdoors, it was important to take steps to reduce mosquito bite risk.

“Mosquitoes thrive in wet, warm conditions like those that much of NSW is experiencing,” Mr Byleveld said.

“Mosquitoes in NSW can carry viruses such as Japanese encephalitis (JE), Murray Valley encephalitis (MVE), Kunjin, Ross River and Barmah Forest. The viruses may cause serious diseases with symptoms ranging from tiredness, rash, headache and sore and swollen joints to rare but severe symptoms of seizures and loss of consciousness.”

“People should take extra care to protect themselves against mosquito bites and mosquito-borne disease, particularly after the detection of JE in a sentinel chicken in Far Western NSW.”

The NSW Health sentinel chicken program provides early warning about the presence of serious mosquito borne diseases, like JE. Routine testing in late December revealed a positive result for JE in a sample from Menindee.

A free vaccine to protect against JE infection is available to those at highest risk in NSW and people can check their eligibility at Japanese encephalitis vaccination.

People are encouraged to take actions to prevent mosquito bites and reduce the risk of acquiring a mosquito-borne virus by:

  • Applying repellent to exposed skin. Use repellents that contain DEET, picaridin, or oil of lemon eucalyptus. Check the label for reapplication times.
  • Re-applying repellent regularly, particularly after swimming. Be sure to apply sunscreen first and then apply repellent.
  • Wearing light, loose-fitting long-sleeve shirts, long pants and covered footwear and socks.
  • Avoiding going outdoors during peak mosquito times, especially at dawn and dusk.
  • Using insecticide sprays, vapour dispensing units and mosquito coils to repel mosquitoes (mosquito coils should only be used outdoors in well-ventilated areas)
  • Covering windows and doors with insect screens and checking there are no gaps.
  • Removing items that may collect water such as old tyres and empty pots from around your home to reduce the places where mosquitoes can breed.
  • Using repellents that are safe for children. Most skin repellents are safe for use on children aged three months and older. Always check the label for instructions.
  • Protecting infants aged less than three months by using an infant carrier draped with mosquito netting, secured along the edges.
  • While camping, use a tent that has fly screens to prevent mosquitoes entering or sleep under a mosquito net.

Remember, Spray Up – Cover Up – Screen Up, to protect from mosquito bite. For more information go to: Mosquito borne diseases.
