Advice for Travellers
Ross River virus (RRV) and Barmah Forest virus (BFV) are uncommon in travellers and cause symptoms that include rash, fever, joint and muscle pains.
For (RRV), the risk is greatest in those planning outdoor activities (particularly camping) in rural areas of Australia, Papua New Guinea and the South Pacific Islands. (BFV) has been found only in Australia.
- Travellers should be aware of the presence of RRV and BFV at their travel destination and practice good insect bite avoidance.
- Warning notices in the media, during outbreaks and in high-risk areas, are given in Australia and should be heeded by travellers.
No vaccines are available and there is no specific treatment for either infection.
