The dengue mosquito, Aedes aegypti, was detected in Tennant Creek in November 2011. A dengue mosquito elimination program was swiftly established by the Northern Territory Department of Health. The program was expected to end in June 2013 but was extended until April 2014, as low numbers of Ae. aegypti were still present in the town. The program is now in its 8th round of property inspections and treatment with no Ae. aegypti detected since June 2013. The program is expected to be declared successful at the end of April 2014.
