Cases of MVE, JE and Kunjin prompt mosquito warning from Department of Health

The Department of Health has urged West Australians to cover up and use repellent over the Easter holidays as the risk of mosquito-borne disease rises.

Murray Valley encephalitis (MVE), Kunjin and Japanese encephalitis (JE) viruses have been detected across a wide area of WA, and people should take appropriate precautions.

The alert follows a recent case of MVE in the West Kimberley that resulted in the death of a young child.

The child’s case was the second case of MVE reported in WA since 2018.

A significant increase in virus activity was detected across the State through the department’s sentinel chicken surveillance program, including recent detections in the Mid West and Wheatbelt regions.

Department managing scientist Dr Andrew Jardine said these viruses were transmitted to people through the bite of an infected mosquito and could cause serious disease in some cases.

“Many holiday-makers will be travelling over Easter and the school holidays and it is very important to pack an effective repellent and long, loose-fitting clothing for everyone in the family,” he said.

Initial symptoms of MVE and JE include fever, drowsiness, headache, stiff neck, nausea and dizziness, and people experiencing these symptoms should seek immediate medical attention. Symptoms in children may only be fever.

Symptoms of Ross River Virus disease can last for weeks to months, and include painful or swollen joints, sore muscles, skin rash, fever, fatigue and headaches. The only way to diagnose the disease is by visiting your doctor and having a specific blood test.

Dr Jardine suggests avoid being outdoors at dawn and dusk, wear protective clothing, apply repellent containing DEET, and use mosquito nets and screens.
