A man aged in his 70s from northern Sydney died on 23 February in a Sydney hospital, where he had been receiving care for JE since early February.

The man initially presented to the Barham Multi Purpose Service in February with JE symptoms after holidaying in the Murrumbidgee region in January.

This is the state’s third confirmed death from JE since the virus was first detected in NSW in 2022.

An additional case of JE has been identified in a woman in her 60s in northern NSW. She likely acquired the infection on her rural property in Tenterfield Shire and is receiving care in hospital.

NSW Health’s Executive Director of Health Protection Dr Jeremy McAnulty said these developments are a reminder of the importance for people to take precautions against mosquitoes, including vaccination.

“These two cases of JE virus, one of which was infected while travelling for a holiday, shows it is very important that all people take precautions against mosquitoes, not just those living in affected regions,” Dr McAnulty said.

“If you plan on travelling west of the Great Dividing Range, whether for work or holiday, and you plan to spend time outdoors, JE is a risk you must consider.

“Thankfully, there are simple steps you can take to avoid mosquitoes, and there is also a safe and effective vaccine available.”

JE vaccine is available through local General Practitioners, Aboriginal health services and pharmacists to anyone who lives or routinely works in various inland LGAs or high-risk occupations.

NSW Health advises people who meet the eligibility criteria should make an appointment and let the provider know it is for the JE vaccine, as they may require a few days’ notice to order the vaccine.

JE virus is spread by mosquitoes and can infect animals and humans. The virus cannot be transmitted between humans and it cannot be caught by eating pork or other pig products. There is no specific treatment for JE which, in some cases, can cause severe neurological illness with headache, convulsions, reduced consciousness and death.

The best thing people throughout the state can do to protect themselves and their families is to take steps to avoid mosquitoes.

Simple actions you can take include:

• 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 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.
