Ross River Fever - Everything You Need To Know
About Ross River Fever
Ross River Fever is a viral illness, caused by an infection submitted through. It is classified in a group of viruses called arboviruses, which are spread mainly by the bite of infected mosquitoes. The virus was first identified in mosquitoes collected near Townsville’s Ross River in Queensland, but cases have been recorded in all states of Australia.
Where does it occur?
The disease is most common in Australia from January through till May, when mosquitoes are most abundant. About 5000 people are recorded as being infected with the virus in Australia each year, with infections most commonly occurring in rural areas of NSW. People living in warm, humid climates near bodies of water will be most at risk of infection, particularly those in contact with known mosquito habitats. This is because local conditions of rainfall, tides and temperature promote mosquito breeding.
What are the symptoms of ross river fever?
Symptoms usually appear within five to fourteen days of being bitten by an infected mosquito. They can include:
- flu-like symptoms such as fever, chills, headaches and aches and pains in the muscles and joints
- swollen or stiff joints
- general feelings of nausea, fatigue or weakness
- rash on the body, arms or legs
The majority of people will completely recover within six weeks. Others may experience symptoms such as joint pain or tiredness for months.
However, many people (particularly children) will never actually develop symptoms.
What causes Ross River Fever?
The Ross River virus is not contagious and is only spread by mosquitoes. The virus typically lives in native mammals such as kangaroos and wallabies, but can also be found in rodents, bats and horses. Certain types of female mosquitoes will contract the virus if they feed on the blood of an infected animal. The virus then multiplies within the mosquito and is passed to other animals or people when the mosquito feeds again.
Once the virus enters the human bloodstream, it reproduces itself in blood cells and builds up in the muscles, joints and skin, which leads to the symptoms of infection.
How do you prevent ross river fever?
A vaccine to prevent infection from the Ross River virus has been developed, but is yet available.
Protecting yourself and your family from mosquito bites is critical in preventing disease.
- Avoid known mosquito-infested areas, particularly at dawn and dusk when mosquitoes are most active
- When outdoors, cover as much skin as possible with light-coloured, loose fitting clothing and covered footwear
- Use an effective repellent such as Aerogard on all exposed skin, and be sure to reapply regularly as protection wears off from perspiration
- Cover your clothes with a repellent as mosquitoes can bite through material
- Use mosquito coils outdoors and vapourising mats indoors
- Cover all windows, doors and vents with insect screens
- Use screened tents when camping, or sleep under a mosquito net
- Protect your kids by using insect repellents like Aerogard Kids Pump Spray
How do you treat ross river fever?
