Q-Fever - The bug

Caused by a bacteria called Coxiella burnetii. The bacteria infects domestic and wild animals including cats, dogs, cattle, kangaroos and camels through ticks. The ticks excrete the bacteria in their faeces. Coxiella burnetti can infect humans by inhaling, eating (from handling contaminated objects) as well as through broken skin and mucosa. It can survive at 4oC for more than a month and can survive unto 600C. It can survive in air, soil and dust.

Q-Fever - The disease

People who have contracted Q-fever can have a spectrum of conditions from being totally unaware of the infection to severe flu like illness but can also affect liver (causing jaundice), affect the heart, cause severe pneumonia needing ICU care. Some people can also have long term illness leading to tiredness, weight loss as well as pain.
