A significant alert has been raised for residents in the southern regions of New South Wales (NSW) due to the detection of a probable case of Japanese encephalitis (JE), a rare yet potentially severe viral illness. This warning urges local communities to take protective measures against mosquito bites, which are the primary transmitters of this dangerous disease.
Japanese encephalitis can lead to serious neurological complications, including symptoms like intense headaches, confusion, seizures, and a decreased level of consciousness, as outlined by NSW Health officials.
The case under investigation involves a man in his sixties who likely contracted the virus while in the Riverina area towards the end of December.

According to NSW Health, JE was previously identified in sentinel chickens within the Upper Lachlan Shire earlier in the year, suggesting that the virus may be actively circulating in that region. Sentinel chicken surveillance serves as an important tool for early detection of mosquito-borne viruses.
Alison Nikitas, the Director of Public Health for Murrumbidgee and Southern NSW Local Health District, emphasized the importance of awareness and prevention for those living or working in high-risk areas. She recommends that individuals take proactive steps to shield themselves from mosquito bites, including vaccination.
Areas classified as high-risk include Albury, Tamworth, Wagga Wagga, and several others. "There is currently no specific treatment available for Japanese encephalitis, hence it is crucial for anyone residing in or visiting these zones to understand the heightened risk," Ms. Nikitas stated.
Fortunately, a safe and effective vaccine is accessible at no charge for those who live in or regularly work in various inland regions. Individuals can receive the JE vaccine through general practitioners, Aboriginal health services, and pharmacies, but it's advisable to schedule an appointment ahead of time, as it may take a few days to procure the vaccine.
To further minimize the risk of mosquito bites, NSW Health recommends using repellent products containing DEET, picaridin, or oil of lemon eucalyptus on exposed skin, and advises reapplication as necessary. Wearing light-colored, loose-fitting clothing, such as long-sleeved shirts, long trousers, socks, and sturdy shoes is also encouraged, along with avoiding outdoor activities during the peak mosquito hours of dawn and dusk.
Additionally, insecticide sprays and mosquito coils can be effective in repelling these pests; however, they should only be used outdoors in well-ventilated spaces. It's also vital to ensure that windows and doors are fitted with insect screens, eliminating any gaps that could allow mosquitoes to enter the home.
Moreover, NSW Health advises homeowners to eliminate standing water accumulations, such as those found in old tires or empty containers, since these are prime breeding grounds for mosquitoes.
It's essential to note that Japanese encephalitis does not spread directly from person to person or from animals to humans, making awareness and preventive actions all the more important.
