On the 17th February 2004, the mosquito species Aedes aegypti, a vector for dengue fever, was found in routine mosquito trapping in Tennant Creek. This was the first time since the 1950’s that Aedes aegypti had been recorded in the NT. The discovery of Aedes aegypti lead to a massive survey and eradication program within the town to remove the mosquito from the NT involving Medical Entomology Branch (MEB), Environmental Health Department, Tennant Creek Town Council, Julalikari Council, Anyinginyi Congress, Centre for Disease Control and volunteers.
