Normal commensal of rodent oropharynx also in ferrets, weasels, gerbils.
Risk factors for acquisition: crowded urban dwellings (especially kids), lab workers.
Transmission: bite/scratch from rat, mice, squirrels—also cats, dogs, pigs.
Symptoms: incubation ˜10-day fever, chills, HA, N/V, migratory arthralgias, leukocytosis (˜30 K).
Days 2-4 days: nonpruritic maculopapular, petechial, or pustular rash (palms soles, extremities). May be purpuric/confluent.
In 50% pts, polyarthritis (even septic arthritis) with or after onset rash (knees>ankles>elbows>hips). Most symptoms resolve within 2 weeks (even if no abx). Arthritis can persist  for 2 years. Nonzoonotic transmission (orally): aka Haverhill Fever (similar manifestations as RBF). Rodent excrement contaminating water, milk, turkey meat. Milk contamination associated w/ epidemics.
