What is it?
Q fever is caused by the bacteria Coxiella Burnetii.
What to look for
Infection is asymptomatic in at least half of cases. Those who experience symptoms may develop fever, chills, sweats, fatigue, severe headache, weakness, and muscle and joint pain. Complications can include hepatitis, pneumonia and endocarditis. Death is rare.
How is it transmitted?
The bacteria can survive in air, soil and water. It is transmitted to humans by inhaling infected soil and dust. The main sources of infection for humans include cattle, sheep and goats.
Immunising high risk groups (abattoir workers, farmers, stockyard workers, shearers, animal transporters, and others exposed to cattle, camels, goats, and kangaroos or their products) is the best way to prevent Q fever. Before vaccination, serological and skin testing should be performed. If previous infection is confirmed, vaccination is not needed. Vaccination generally provides lifelong protection.
Vaccination is not recommended in those <15 years.
Egg allergy is a contraindication to immunisation.

Welcome to MVEC
The Melbourne Vaccine Education Centre (MVEC) is a new web-based initiative, providing up-to-date immunisation information for healthcare professionals, parents and the public.
It is a collaboration between The Royal Children’s Hospital (RCH) and its Melbourne Children’s campus partners (Murdoch Children's Research Institute and The University of Melbourne) and Monash Health.
MVEC aims to address common queries around vaccines and to promote the benefits of immunisation for both children and adults.
