Background
- 6 avian serovars (A-F) and 2 mammalian isolates (WC and M56)
- Reservoirs: birds (465 species), duck, geese, turkeys, cattle, muskrats
- Transmission: inhalation from aerosolized urine, feces, dried feces, eye secretions. Person-to-person transmission is possible but rare.
- Incubation period usually 5-14 days but can be up to 1 month

- Complications: myocarditis, endocarditis, icterus, encephalitis, ARDS, MODs
Differential Diagnosis
Workup
- CBC-leukopenia in 25% of cases
- Chemistry
- CRP
- LFT
- CXR-usually lower lobe consolidation
- Sputum culture
Management
- Doxycycline 100mg PO Q12h x 10-14 days OR
- Azithromycin 500mg PO Qday x 7 days
Disposition
- Generally may be discharged
