Answer 1

The disease presents as a rapidly progressive, severe, necrotizing pneumonia, accompanied by fever, nonproductive cough, and myalgias.
The onset is abrupt, after an incubation period of 2 to 10 days.
Within 2 days, most patients develop a persistent high fever and respiratory rales.
It involves primarily the lower respiratory tract, although it is often associated with multi-systemic extrapulmonary manifestations. Afflicted patients may sometimes have gastrointestinal symptoms, liver function abnormalities, renal failure , central nervous system complications and cutaneous manifestations which may include erythematous, maculopapular or petechial skin lesions.
Those who abuse alcohol and smoke heavily are also at increased risk.
The organism has been recovered from soils, ponds, water systems, and air conditioning systems.
