A northern Sydney man has died after contracting Japanese encephalitis while on holiday in southern NSW, marking the third confirmed death from the mosquito-borne disease in the state since 2022. The man, in his 70s, likely contracted the disease while holidaying in the Murrumbidgee region in January, according to NSW Health. This recent death has prompted health authorities to urge people to take extra precautions when visiting areas where Japanese encephalitis is present. NSW Health has also reported an additional case of Japanese encephalitis in a woman from northern NSW, who likely caught the infection at her rural property in Tenterfield Shire.

Japanese encephalitis is a mosquito-borne disease that can cause severe neurological illness, including headache, convulsions, reduced consciousness, and death. The disease is spread to humans and animals by mosquitoes, and there is no specific treatment for it. However, people can prevent becoming infected by using insect repellents that contain DEET, picaridin, or oil of lemon eucalyptus. A vaccine is also available to prevent contracting Japanese encephalitis, and it is recommended for people who work in high-risk locations or occupations. NSW Health has urged people to avoid going outdoors during peak mosquito times, especially at dawn and dusk, wear loose-fitting and long-sleeve clothing, and cover doors and windows to prevent mosquito bites.

The recent cases of Japanese encephalitis in NSW have caused concern among health authorities, who are urging people to take precautions against mosquitoes. Entomologist Cameron Webb told Yahoo News that those infected with the disease are "incredibly unlucky", as the rate of symptom development even when bitten by an infected mosquito is low. However, the case-fatality rate among those with Japanese encephalitis can be as high as 30 per cent, according to the World Health Organisation, making it a serious disease that needs to be taken seriously. NSW Health's Executive Director of Health Protection Dr Jeremy McAnulty said that people should consider being vaccinated against the virus if they are heading to high-risk areas, and that simple steps such as using skin repellents and wearing long-sleeve shirts and long pants can help ward off unwanted bites.

Here are some key points to note about Japanese encephalitis: * The disease is spread to humans and animals by mosquitoes * There is no specific treatment for Japanese encephalitis * A vaccine is available to prevent contracting the disease * People can prevent becoming infected by using insect repellents and wearing protective clothing * The case-fatality rate among those with Japanese encephalitis can be as high as 30 per cent * The disease is more common in the Murray Darling Basin region of Australia, which includes parts of NSW, Victoria, Queensland, and South Australia. The outbreak of Japanese encephalitis in Australia has highlighted the importance of taking precautions against mosquitoes, especially in high-risk areas.

In conclusion, the recent death from Japanese encephalitis in NSW has prompted health authorities to urge people to take precautions against mosquitoes. While the disease is rare, it can be serious and even fatal, making it essential to take steps to prevent infection. By using insect repellents, wearing protective clothing, and considering vaccination, people can reduce their risk of contracting Japanese encephalitis and stay safe during the mosquito season.
