Australians are experiencing a rise in the dangerous Japanese encephalitis virus, with a recent detection in a mosquito trap near Melbourne. This marks the first reported case of the current Australian summer, following an outbreak in 2022.
The virus, transmitted by mosquitoes, can cause severe symptoms including fever, vomiting, and seizures. In rare instances, it leads to fatal brain inflammation. While most infections are asymptomatic or mild, its potential severity is a significant public health concern. Pig farms have been identified as key vectors for the virus's spread.
Rising global temperatures and increased precipitation, linked to pollution, are contributing to a surge in mosquito populations and the diseases they carry. Researchers are developing novel mosquito control strategies, such as using soap to immobilize them and exploring new fungal treatments. Public health officials recommend personal protective measures like using insect repellent and wearing light-colored clothing to prevent infection.
