Murray Valley encephalitis: Potentially fatal disease detected in mosquitoes in WA, Kimberley tourists warned

WA Health has issued a warning to locals and anyone travelling throughout the State to protect themselves against a potentially fatal disease found in mosquitoes.

The warning comes after Murray Valley encephalitis was found in mosquitoes and sentinel chickens for the first time this year in the Kimberley region.

Locals are urged to protect themselves against mosquito bites as MVE is a serious and potentially fatal disease.

Symptoms include fever, drowsiness, headache, stiff neck, nausea and dizziness. Fever may be the only sign of early infection in children.

Last year, a child died after significant MVE activity was detected in the Kimberley region.

Ross River virus — also found in mosquitoes — was also detected for the first time this year in January in Perth’s southern suburbs.

Symptoms include painful or swollen joints, sore muscles, skin rash, fever, fatigue, and headaches.

Anyone experiencing these symptoms should seek urgent medical advice.

Managing scientist Dr Andrew Jardine said recent activity followed significant rainfall in the region, creating ideal conditions for mosquitoes.

“Ross River and Murray Valley encephalitis viruses are only spread by mosquitoes – so the message is simple: protect yourself from being bitten,” he said.

“Many people are bitten when fishing or camping – make sure you pack an effective repellent and follow all the advice to avoid mosquito bites.“While the risk of getting infected and becoming sick is low, the illness caused by the virus can be severe in some cases.”
