A far south coast town is being urged to be on the alert for a potential measles outbreak.
The Southern New South Wales Local Health District says an Eden woman did not know she had the disease and spent a lot of time in the community over recent weeks.
The District's Director of Public Health, Tracey Oakman, says anyone who develops symptoms should see a doctor immediately, and should phone ahead so they can be kept separate from other patients.
"It's important to realise that the symptoms of measles can be fever, tiredness, a runny nose, cough, sore and red eyes, and you can get a blotchy rash," she said.
"And you can actually get quite serious complications from measles so it's really important if people develop those symptoms they go and get diagnosed.
It is in Australia a fairly rare disease these days, but it is highly infectious, and someone can actually be in a room where someone with measles has been in the previous two hours and left and still come down with it.
Ms Oakman say many people in Eden may have been exposed to measles over recent weeks.
"I think it's fair to say that she would have come into contact with a number of people in the community," she said.
"We don't know necessarily who they all are, so it's just important that people in the community be aware of measles.
"It is in Australia a fairly rare disease these days, but it is highly infectious.
