Q-FEVER
Q fever is a disease caused by infection with Coxiella burnetii, a bacterium that affects both humans and animals. This organism is uncommon but may be found in cattle, sheep, goats and other domestic mammals, including cats and dogs. The infection results from inhalation of contaminated particles in the air, and from contact with the milk, urine, feces, vaginal mucus, or semen of infected animals. The incubation period is 9–40 days. It can be considered the most infectious disease in the world, as a human being can be infected by a single bacterium.
