Topic: Kunjin Virus Disease
Description
Kunjin virus disease is caused by a virus which is spread by the bite of an infected mosquito. Although only a small number of cases of Kunjin are reported annually, the virus is known to occur in many parts of Australia particularly in tropical northern regions.
Symptoms
Symptoms of Kunjin virus disease vary. While most infected people do not develop any symptoms others may experience fever, headache, muscle pain, swollen lymph nodes, fatigue and rash. Inflammation of the brain (encephalitis) characterised by fever, headache, neck stiffness, irritability, confusion, drowsiness and seizures (fits) can also occur.
Transmission
The main mosquito associated with the spread of Kunjin virus is Culex annulirostris which breeds in fresh water environments. It is thought that wading birds, such as herons, are associated with spread of the virus to mosquitoes. The virus cannot be spread directly from person to person.
Treatment
There is no specific treatment for the disease. Your doctor or health care professional can advise you on the most appropriate management of symptoms.
Prevention
There is no vaccine for Kunjin virus disease. The only way to prevent the disease is to prevent being bitten by infected mosquitoes.
To prevent being bitten by mosquitoes:
- Avoid being outside when mosquitoes are most active from just before sunset until dawn.
- Wear loose, light-coloured clothing with long sleeves.
- Use personal insect repellent containing DEET or picaridin in accordance with the manufacturer’s recommendations noted on the label.
- Ask a pharmacist for an inspect repellent that is suitable for young children and babies. It’s best to use physical barriers such as nets on prams and cots to protect infants less than 3 months of age.
- Use flying insect spray, mosquito coils or plug-in insecticide devices to kill mosquitoes indoors.
- Use bed nets if available.
- Make sure insect screens are in good order.
