Health authorities are warning the public to be alert for measles symptoms after a man diagnosed with the highly infectious disease visited a number of locations in Sydney’s inner west, north-west and eastern suburbs.

The man is believed to have been infectious from Friday December 27. He spent December 28 at Bondi Beach before returning home to Sydenham. He also spent time around Central Station and Marrickville Metro over the following days.

It is not clear how the man in his 20s contracted the measles. NSW Health said he had not recently returned from overseas and had no known links to previously identified measles cases.

Sydney Local Health District’s Public Health Unit is identifying people who may have

been in contact with the man and will arrange preventive treatment if required.
