Barmah Forest virus is a virus currently found only in Australia. Although there is no specific treatment for infection with the Barmah Forest virus, the disease is non-fatal and most infected people recover.[1][2] The virus was discovered in 1974 in mosquitos in the Barmah Forest in northern Victoria.[3]

Transmission[edit]

The virus can only be transmitted to humans by bites from infected mosquitos. Direct contact with an infected person or animal does not cause infection.[4] The virus is hosted mainly by marsupials, especially possums, kangaroos and wallabies.[2]

Symptoms[edit]

Symptoms include fever, malaise, rash, joint pain, and muscle tenderness. Fever and malaise generally disappear within a few days to a week, but other symptoms such as joint pain may continue for six months or longer.[1][5]

The Barmah forest virus causes similar symptoms as the Ross River virus, though they usually persist longer in persons infected with the latter.[2][4]
