The Health Department is urging people with flu-like illness to avoid visiting patients at hospital.
It comes as the number of reported cases of influenza in Tasmania this year reaches 1501 - more than three times the total number of cases reported in 2018.
Executive Director of Operations for the state's South Susan Gannon said the advice of the Health Department was that it had been an "unremarkable" flu season so far.
However, she said there was considerable influenza in the community, as occurs each year around this time.
"If you are unwell and your visit is unavoidable, immediately tell a nurse when you arrive at the hospital that you may be unwell to seek further advice about your visit," Ms Gannon said.
"Most people with influenza do not need to come to hospital for treatment unless they are having difficulty breathing or experiencing other complications arising from the flu.
If you have flu-like symptoms consider seeing your GP - please call ahead to let the surgery know of your illness so they can advise you."
Ms Gannon said there was a range of measures in place to minimise the risk of flu spreading within hospitals, including managing those patients affected and ongoing ward cleaning.
"Tasmania's health agencies have worked together in the lead up to winter to increase capacity at each of our major hospitals around the state for Tasmanians in need of care," she said.
"A number of actions have been implemented under our winter plan, including raising awareness of winter illnesses and their prevention."
