Ross River virus is Australia’s most common and widespread
arbovirus. It causes epidemic polyarthritis and is associated
with significant morbidity and cost to society.
This article aims to increase clinicians’ awareness of the
epidemiological and clinical features of Ross River virus and
provide information regarding prevention, diagnosis and
Ross River virus occurs throughout Australia and numerous
outbreaks have occurred. Most cases occur in northern
Australia during the wet season, and individuals with high
exposure to mosquitoes are most at risk. Arthralgia is the most
common presenting symptom and is usually associated with
rash, fever and lethargy. No treatment alters the course of the
illness, although patients may benefit from simple analgesics
or nonsteroidal anti-inflammatory drugs. Symptoms usually
resolve within 6 months. Personal protective measures against
mosquitoes are an important prevention strategy.
