Person dies from rare Murray Valley Encephalitis virus in Western Australia
A person has died after contracting Murray Valley Encephalitis, a rare mosquito-borne virus, following travel in the West Kimberley region of Western Australia. The individual was likely exposed in early to mid-May and was transferred to a Perth hospital before passing away. The death highlights ongoing virus risk in northern WA as the tourist season begins, with health authorities urging travellers to protect themselves from mosquito bites.
The Western Australia Health Department has confirmed the state's first reported Murray Valley Encephalitis (MVE) death this year, involving a person likely exposed to the virus in the West Kimberley, approximately 2,000 kilometres north of Perth, in early to mid-May. The individual was transferred to a Perth hospital, where they subsequently died. MVE is endemic to northern WA and is transmitted to humans through infected mosquitoes; there is currently no vaccine available. While serious complications are rare — many infected individuals experience no symptoms or only mild illness — the virus can cause severe brain inflammation, potentially resulting in permanent neurological damage or death. Health authorities note that risk is highest during and immediately after the wet season, but warn that infected mosquitoes may continue to pose a threat into July. The Department of Health's sentinel chicken and mosquito surveillance programs have been detecting MVE and other flavivirus activity across the Kimberley and Pilbara since the start of the year. With thousands of tourists expected to travel to northern Australia in coming months, officials are urging residents and visitors to take precautions against mosquito bites.
What's missing
Neither source specifies whether the deceased had any underlying health conditions that may have increased susceptibility to severe disease, nor do they provide data on the total number of MVE cases detected in WA this season beyond the single fatal case.
How coverage differed
ABC Australia identified the deceased only as an adult, while the National Indigenous Times specifically identified the person as an Aboriginal woman, providing additional demographic context absent from the ABC report.

Chicago Woman's Five-Year Symptom Journey Leads to Rare Brain Tumor Diagnosis
Melony Aponte, 26, was diagnosed with a 4.5-centimeter acoustic neuroma after five years of symptoms she attributed to stress, COVID-19, and aging. The rare, noncancerous tumor—affecting roughly one in 100,000 people—had grown large enough to compress her hearing and balance nerve before it was identified via MRI in March 2025. Her case highlights how acoustic neuroma symptoms can mimic common conditions, potentially delaying diagnosis for years.
Study Finds Aging Shifts Walking Strategy Toward Stability at the Cost of Efficiency
A new study from Flinders University and the University of Canberra found that as people age, their bodies adopt a 'safety-first' walking pattern that prioritizes balance over efficient movement. Researchers analyzed gait data from 107 healthy adults aged 26 to 86, identifying increased ankle muscle co-contraction and reduced push-off power as key age-related changes. The findings suggest that fall prevention programs should target balance and coordination, not just muscle strength.
Tick Populations Surge in Urban Areas Across Northeast
Experts across the northeastern United States and Canada are warning of an unusually early and widespread tick season, with disease-carrying ticks increasingly found in urban parks and green spaces. Lyme disease cases in Canada reached a record 7,105 in 2025, up from 5,809 the previous year, while U.S. cities including Philadelphia, Pittsburgh, Washington D.C., and New York are reporting rising tick activity. The expansion poses a public health challenge because urban residents are less likely to take tick-bite precautions than those in rural areas.
