The Department of Health has issued a health alert, urging the Western Australian community to be aware of a confirmed measles case in a returned traveller from Bali.
The person visited several public venues in the metropolitan area while infectious with measles between 2 February and 7 February.
This included the Drake concert at RAC Arena on Tuesday night, 3 Quarters Topped Up Café in East Perth, GP After Hours Clinic in Mount Nasura and several other locations.
A full list of exposure locations can be found via the health alert.
Director of Communicable Disease Control, Dr Paul Armstrong, said anyone with signs or symptoms should be tested and their doctor should notify the Department of Health.
"Anyone who has visited an exposure location during the dates and times listed should monitor for symptoms and, if symptomatic, wear a mask and seek medical care," Dr Armstrong said.
"Before presenting at a GP clinic or emergency department, call ahead so staff can ensure you do not infect other patients and staff."
Early symptoms include fever, tiredness, cough, runny nose, and sore eyes, followed by a red non-itchy rash three or four days later. The rash usually starts on the face and spreads to the rest of the body.
Community members who have visited an exposure location during the times listed should watch for symptoms for 18 days after the potential exposure.
These locations may be updated. People are encouraged to monitor the Department of Health website for updated advice.
Due to high vaccination coverage, measles has been eliminated from Australia for more than 25 years. Imported cases or small outbreaks still occur at times, generally due to residents or visitors who get infected while overseas.
Anyone planning overseas travel should see their general practitioner or a travel doctor to discuss appropriate vaccinations prior to travel.
People who are concerned they may have measles and require medical advice can contact healthdirect on 1800 022 222.
