Sydney. A deadly virus transmitted by mosquito bites was attacking Western Australia. The virus is reportedly NOT have a prophylactic drug or vaccine.

Western Australian Health Department says at least six people have been diagnosed with the virus Murray Valley encephalitis (MVE), which is a virus that can cause serious brain inflammation. The warning alert was also issued to anyone who will travel to the north or east of Perth.

“MVE activity is rare but potentially fatal and Kunjin virus have been detected in the Kimberley, Pilbara, Gascoyne, Goldfields, Midwest and central Wheatbelt region, indicating widespread virus activity,” said Sue Harrington, a medical entomologist, as reported by smh.com.au, Friday (20/05/2011).

Harrington explained, Murray Valley encephalitis virus and Kunjin virus carried by mosquitoes. Risks that occur when infected one will become unhealthy or could be severe, so people should take reasonable measures to avoid mosquito bites.

“MVE initial symptoms are fever, drowsiness, headache, stiff neck, nausea and dizziness,” said Harrington.

In severe cases, continued Harrington, the patient may be in a coma, suffered permanent brain damage and died.

“In children, fever might be just the first symptoms, so parents should seek medical help, especially if the child also experience sleepiness, irritability and did not want to eat,” said Harrington.

Kunjin virus usually causes a milder disease than MVE, but can cause headaches, neck stiffness, fever and delirium.

“There is no specific treatment or vaccines for diseases that are transmitted by mosquitoes, so it is important for care to prevent being bitten by mosquitoes,” said Harrington.

According to Harrington, controlling mosquitoes in most rural areas of Western Australia is NOT possible because of their large size and inaccessibility of natural mosquito breeding habitat.

“It’s important for people to prevent mosquito bites by avoiding going out at night, wearing mosquito nets and wear protective clothing outside with long sleeves,” Harrington closed.
