Only one case of Ross River Fever has been detected in Tasmania so far this year.
The mosquito-borne virus is spreading throughout mainland Australia, with 857 infections detected in Victoria since January 1, 2017.
This week, The Age has reported that the virus has spread to the south-east Melbourne suburbs of Frankston and Casey.
Last year, Tasmania received a total of seven detected cases of the virus.
The worst outbreak in the state was in 2002, when it spread across the Sorell area, in the state’s south, infecting 117 people.
The outbreak hit from mid-February to early March, and was attributed to spring tides and high summer rainfall that encouraged the growth of a saltmarsh in the area.
Previous outbreaks were in the mid-to-late 1990s, on the East Coast.
The symptoms of Ross River Fever include a fever, headache, aching muscles and joints, and fatigue.
Occasionally, a rash will develop.
The virus is not considered fatal, but its symptoms can linger for months.
