A state-wide measles alert has been issued in Queensland after a mine worker was diagnosed with the potentially deadly virus.

Queensland Health says the central Queensland man probably caught the virus during a recent holiday in Asia and may have passed it on to colleagues.

He had contact with fellow mine workers at the Moranbah mine camp while he was contagious from April 25 to May 6, acting senior director of the communicable diseases unit Dr Stephen Lambert says.

He was in the dining room of the Grosvenor Village camp around April 29 and 30 between 6.30pm and 7.30pm (AEST).

Queensland Health believes many of the mine workers he had contact with have returned to their homes around the state, potentially spreading the virus.

Dr Lambert says anyone who thinks they might have been exposed to the virus should make sure they're protected against measles and seek medical advice if symptoms develop.

Queensland Health is urging anyone born since 1966 who hasn't had two doses of the measles vaccine - or actually had the virus - to get the free vaccine from a GP.

However, pregnant women shouldn't get the vaccine.

"Queensland Health will continue to actively investigate this case and do whatever it can to prevent further transmission," Dr Lambert said in a statement on Wednesday.
