This thesis investigated specific cases of Q fever in both children and adults where there were unusual presentations, including whole families infected, and a serve case in which the patient had. Q fever is a zoonotic disease caused by the rickettsial organism Coxiella burnetii[1-3]. The most common reservoirs for C. burnetii are domesticated ruminants, primarily cattle, sheep, and goats. Humans typically acquire Q fever by inhaling infectious aerosols and contaminated dust generated by animals or animal products. Although Q fever. Q fever is a disease caused by the bacteria Coxiella burnetii.This bacteria naturally infects some animals, such as goats, sheep, and cattle. C. burnetii bacteria are found in the birth products (i.e. placenta, amniotic fluid), urine, feces, and milk of infected animals. People can get infected by breathing in dust that has been contaminated by infected animal feces, urine, milk, and birth.

Q fever is an infectious disease of animals and humans caused by a species of bacteria called Coxiella burnetii. This organism is very durable it can survive for months in the environment. Sheep, goats, and cattle can carry the organism. The bacteria\ can be shed by these animals in feces, urine, milk, and in the birthing fluids and membranes Q fever has an incubation period of approximately 2 to 3 weeks. Acute symptoms are onset of fever, peaking in 2 to 4 days near 40°C and gradually declining for 1 to 2 weeks, accompanied by malaise, anorexia, myalgia, weakness, and intense headache. Liver damage with hepatomegaly occurs, often leading to hepati Q fever is a severe, acute febrile illness, which is a major problem in Australia and around the world. It is a zoonotic disease (i.e. spread from animals to humans) caused by the organism Coxiella burnetii. Cattle, sheep and goats are the main reservoirs for infection in humans malaise, fever, fatigue, myalgias, dyspnea, nausea, and diarrhea (Table 2). The incubation period for Q fever was difficult to determine as most people had many contacts with goats.

Although the majority of people with acute Q fever recover completely, a post-Q fever fatigue syndrome has been reported in up to 20% of acute cases. This syndrome is characterized by constant or recurring fatigue, night sweats, severe headaches, photophobia, myalgia, mood changes, and difficulty sleeping The incubation period for acute Q fever varies, but it is generally 2-3 weeks.

Educatio QFP : Q fever, a rickettsial infection caused by Coxiella burnetii, has been recognized as a widely distributed zoonosis with the potential for causing both sporadic and epidemic disease. The resistance of C burnetii to heat, chemical agents, and desiccation allows the agent to survive for extended periods outside the host. The infection is spread by the inhalation of infected material, mainly. pets. Q fever may cause acute flu-like illness, pneumonia, hepatitis, and chronic endocarditis in humans and abortion or infertility in animals. It has major importance for public health.
