Australian Encephalitis

In Australian encephalitis a person can sometimes have a very mild case and usually is unaware that they are sick, in fact only 1 in 500 people become seriously ill. There is often a sudden onset of fever, headache, dizziness and nausea and vomiting. Over the next few days there is an increased level drowsiness, change in the level of consciousness, convulsions (epilepsy), coma and death may follow. Even when people do not die they still can suffer permanent brain damage from the encephalitis. There isn't even a vaccine! So take the usual precautions for avoiding mosquito bites. Also make sure to empty out all containers that are capable of holding water. Water is a major breeding ground.

Ross river's and Barmah forerst's virus disease is also known Epidemic Polyarthritis and there is a good reason for that because the symptoms are joint pain in your wrists, toes, fingers, ankles and knees also, rashes, burning or a tingling sensation, which can last from months to years. In Ross river disease the symptoms are apparent 3-21 days after a bite and recovery is within a month. In Barmah Forest disease the rash may be worse than in Ross river disease but the arthritis may not be so severe. Dengue fever's symptoms are loss of appetite, vomiting, nausea, pain behind the eyes, severe headache, rash, high fever, mild illness, hemorrhagic fever, bleeding, bruising and 5% of people die from it.
