Director of Public Health Tracey Oakman said there have been three confirmed cases of Q fever in the MLHD area - which includes Moama and Mathoura - to date this year.
In 2018, there were 15 confirmed cases of the disease in the area.
“Q fever is a serious bacterial infection caused by inhaling dust particles contaminated by infected animal secretions that does not just affect farmers or people who deal with livestock,” said Ms Oakman.
“The infection is carried by cattle, goats, sheep and other domesticated and wild animals, so people who work on the land are most at risk.
“However, the bacteria can easily be carried on farm tools or work clothes and brought into the family home."
Ms Oakman said across Australia there has been an increase in Q fever cases over the past several years and the emergence of the disease in groups who do not regularly work on farms or abattoirs, such as Aboriginal people, itinerant workers and contractors.
Q fever symptoms often appear like severe flu, with high fevers and chills, sweating, severe headaches, muscle and joint pains and extreme fatigue.
Chronic lethargy can remain for months after treatment.
Ms Oakman said a single dose vaccine is recommended for people who work in high risk occupations and anyone over 15 years who has the potential to be exposed to Q fever.
