 - One of five who are exposed develop symptoms.
 - The initial symptoms include fever, chills, severe headache, back pain,
   myalgia, nausea and prostration. These symptoms correspond to the viremic
   phase and are followed by transient (up to 24 hours) remission. With return
   of the fever comes the toxic phase of the infection.

þ Q Fever
 - Epidemiology
  + Interestingly, the presentation of acute Q fever may differ with
    geography.   In northern Spain, pneumonia is a common finding whereas in
    southern Spain, hepatitis predominates.

 - Acute Q fever
  + Acute Q fever is generally a self-limited illness, and mortality from
   acute Q fever is low.  Even patients ill enough to require hospitalization
   have a mortality of only 1%.
 - Chronic Q fever
  + However, chronic Q fever has a higher mortality rate (about 25%).
