Physicians investigated these patients but no cause was able to be identified. To complicate matters, there wasn’t any consistency between those who got sick, the area where they worked in the abattoir nor the animals with which they worked with.

It would take significant investigative skills and an outbreak in the United States to confirm the diagnosis. Today, the causative agent is called Coxiella burnetti.
This is the story of Q fever.
