The Department of Health is warning people to cover up and protect themselves against mosquitoes, as Murray Valley encephalitis (MVE) and Kunjin (KUN) virus activity has been detected in the NT.
KUN and possibly MVE virus activity has been detected in the Katherine region, with MVE virus activity also detected in the Barkly region through the flavivirus surveillance program run by the Department of Health in liaison with the Department of Primary Industry and Fisheries.
Medical entomologist, Nina Kurucz explained that the MVE and KUN viruses can be transmitted by the common banded mosquito, which is active at night. The high risk period for MVE virus transmission is March to the end of June.
Ms Kurucz advised that the risk of contracting the virus in major urban NT centres is considered relatively low at the moment, as routine mosquito surveillance carried out by DoH shows low numbers of common banded mosquitoes. However, she also explained that high mosquito numbers can still occur close to swamps, wetlands and creeks, increasing the risk, especially at the end of the wet season, when fish and other mosquito predators have restricted or no access to pooled water where mosquitoes breed.
“With Territorians traditionally enjoying camping and fishing trips at the start of the dry season, mosquito bite prevention is essential to prevent mosquito-borne diseases,” Ms Kurucz said.
People in the NT are encouraged to cover up, use repellent and avoid outdoor exposure around mosquito prone areas, such as creeks and wetlands – especially after sundown, until the end of June.
To minimise the risk of mosquito borne disease you should:
especially ensure that children are protected against mosquito bites.
avoid outdoor exposure around dusk, and at night, within 2 km of swamps, creeks, rivers, billabongs and other flooded or low lying areas.
use mosquito coils, mosquito lanterns, and apply barrier sprays containing bifenthrin in patio and outdoor areas near houses.
use mosquito proof accommodation and camping facilities at night.
wear light-coloured clothing with long sleeves, long trousers, and ankle protection with socks.
use a protective mosquito repellent containing 20% DEET or picaridin and apply as per label advice. Gels and creams usually provide better protection.
