New South Wales has reported its first death from Japanese encephalitis (JE) since May 2022, after a man in his 70s succumbed to the virus. This tragic occurrence highlights the continued threat of this mosquito-borne illness, which has taken three lives since its first detection in the state.
The man, hailing from northern Sydney, passed away on February 23, 2025, after being hospitalized since early February for JE. Authorities believe he contracted the virus during his holiday in the Murrumbidgee area. "NSW Health expresses its sincere condolences to his loved ones," the department stated. The situation is compounded by the news of another case, involving a woman in her 60s who is currently receiving treatment after likely contracting the virus on her property in Tenterfield Shire.
Japanese encephalitis is transmitted to humans through mosquito bites, with the disease posing serious health risks, including severe neurological complications. Symptoms can range from headaches to convulsions, and unfortunately, there is no specific treatment available. "There is no specific treatment for JE, which, in some cases, can cause severe neurological illnesses, including headaches, convulsions, reduced consciousness, and death," added NSW Health.
“These two cases of JE virus, one of which was infected whilst travelling for a holiday, shows it is very important all people take precautions against mosquitoes, not just those living in affected regions,” urged Dr. Jeremy McAnulty, Executive Director of Health Protection at NSW Health. He stressed the importance of awareness among travelers and residents alike, particularly for those venturing west of the Great Dividing Range.
Dr. McAnulty provided practical advice for residents and travelers alike, urging the use of mosquito repellents and caution during peak mosquito activity times, typically at dawn and dusk. The health department emphasizes taking steps to reduce exposure to mosquitoes, such as wearing appropriate clothing and using screens on windows and doors.
“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 considerate,” Dr. McAnulty noted. Thankfully, there are simple steps you can take to avoid mosquitoes, and there is also a safe and effective vaccine available.
The public is being reminded of the importance of vaccination as the JE vaccine is available free of charge for residents who live and work in areas deemed to be at high risk. Vaccination serves as one of the most effective preventatives against this dangerous disease.
Doctors recommend those eligible to schedule their appointments for the JE vaccine as precautionary measures against the viral infection. It is emphasized to inform healthcare providers about the intent to get the vaccination so they can prepare the necessary resources.
Overall, these recent cases of JE serve as grave reminders to the public about the disease’s potential risks. People are encouraged to stay informed and cautious, particularly as reports of the virus continue to emerge from various regions of New South Wales. The community should prioritize safety and public health to combat this mosquito-borne threat.
