Q fever

Q fever, caused by the rickettsial organism Coxiella burnetii, is found in at least 51 countries on five continents. The primary reservoirs are cattle, sheep, goats, and ticks, but many species of animals, both wild and domestic, are susceptible to infection. Humans are usually infected by inhalation of aerosolized particles.
