<p>The Murray Valley Encephalitis virus - which causes inflammation of the brain - has led to hospitalisation of at least six Australians, Western Australia Today reported.<br /><br />The virus causes fever, nausea and dizziness. In severe cases, victims can experience delirium or lapse into coma.<br /><br />The two deaths have led the health department to issue a stern warning about the virus.<br />"It causes inflammation of the brain. People have suffered paralysis and brain damage of varying degrees. Every case is very significant, because about one-quarter of all cases die, and of those that survive they're left with severe nerve damage that can result in paralysis," a spokeswoman said.<br /><br />There is yet no cure for the virus, nor a vaccine to prevent infection, she said.<br />In addition to the Murray Valley Encephalitis virus, mosquito-borne Kunjin, Ross River and Barmah Forest viruses are also causing infection in the country.</p>
