Several people infected out of a population of over 23 million hardly constitutes an epidemic.

There is a vaccine available for Q fever, as with childhood immunization, some at risk people simply refuse to use it.

Some people want to blame the government for everything from climate change to whooping cough.

we spent 2 mths on a cattle property in QLD in 2012 where both husband and wife were recovering from Q fever. 3 weeks after leaving and staying with friends at Warragul Vic. Barry was unwell with a severe headache and light sensitivity - took him to A+E at the local hospital where they thought he had meningitis despite me suggesting it might be Q fever. No-one knew anything about Q fever as it is rare in Victoria and often does not show up in initial blood tests. After several days in hospital a subsequent blood test 2 weeks later confirmed it was Q fever. This was followed a month later by shingles which I'm sure was as a result of his immune system being effected by the Q fever.
The unfortunate thing was that prior to going to the property he asked a local Dr. about immunisation and was told it's too complicated a process as blood tests are needed prior to immunisation and that he was unlikely to contract it.
