TWO confirmed cases of measles have prompted a warning to anyone who visited Mildura Central shopping centre on two separate dates this month.
Department of Health and Human Services (DHHS) spokesman Bram Alexander said two men in their 20s had been diagnosed with the disease and were assessed and treated at Mildura Base Hospital.
He said both men were from Samoa, were known to one another and were "recovering at home".
"There is a substantial outbreak of measles currently in Samoa," Mr Alexander said.
"Our advice is, anyone planning overseas travel should ensure they've had their vaccinations appropriate for travel.
"The should include MMR (measles, mumps and rubella vaccine). Infants as young as six months of age can receive (the vaccine)."
DHHS said anyone who was at Mildura Central on Sunday, November 17, between 1pm and 4pm, or on Tuesday, November 19, between 6pm and 9pm, may have been exposed, with potential symptoms developing seven to 18 days after exposure.
It's the second confirmed outbreak in Mildura this year, after an infant, who was too young to be vaccinated, was treated for the disease at Mildura Base Hospital in January after visiting a number of public venues across Sunraysia.
Mr Alexander said anyone in the region who felt they may be affected by measles should contact their GP.
"Ring ahead and say you think you may have measles," he said.
"The GP can then isolate you appropriately away from other patients so you're not spreading the disease."
Measles is a highly infectious viral disease that can cause serious illness, particularly in very young children and adults.
People can develop pneumonia and other serious complications from the disease and often needed to be hospitalised.
The illness usually begins with common cold symptoms such as runny nose, red eyes and a cough, followed by fever and rash.
This year there have been 48 confirmed cases of measles in Victoria.
Almost all cases involve people who aren't fully immunised, who have travelled overseas or who have been contact with travellers from overseas.
A large outbreak of measles continues to affect Asia, the Pacific Islands, Europe and America.
Samoa and New Zealand are also experiencing a widespread outbreak of measles with more than 2000 cases notified this year.
