Etiology
infection with Yersinia pestis
Epidemiology
- more prevalent in New Mexico, Arizona, Colorado & California than other states
- great plague of Europe 1400-1600 killing 25% of population
- spread from wild rodents & occasionally cats either directly or by fleas
- primarily a disease of rodents
- pneumonic plague is transmitted through aerosolized Yersinia pestis or person-to-person transmission via respiratory droplets[4]
- 10-15 cases in USA annually[6]
- outbreak of 4 cases in June & July of 2014 in Colorado origating from an infected dog[8]
- 11 cases April-August 2015 in Arizona, California, Colorado, Georgia, New Mexico, & Oregon
Clinical manifestations
- incubation period is 2-7 days
- 3 clinical syndromes
- pneumonic plague from inhalation of Yersinia pestis
- fulminant lethal form
- sudden onset high fever
- pleuritic chest pain
- productive cough
- hemoptysis
- bubonic plague is the most common form (85%)
- purulent lymphadenitis near the site of inoculation
- intensely painful group of swollen lymph nodes (bubo)
- acral gangrene[11]
- septicemic plague can arise from pnuemonic plague or bubonic plague
- pneumonic plague from inhalation of Yersinia pestis
- general
- high fever
- headache
- lymph node enlargement (bubo, axilla & groin)
- petechiae
- hemorrhage from mucous membranes
- cough
- tachypnea
- pneumonia (10-20%)
- sepsis
- case report[9]
- fever
- cough with scant hemoptysis
- chest pain
- myalgias
Laboratory
- leukocyte count > 15,000/mm3
- diagnosis made from blood, lymph nodes & sputum
- Giemsa staining
- gram-negative coccobacilli with bipolar staining (closed safety pin appearance)
- culture
- direct fluorescent antibody
- Giemsa staining
- serology
Radiology
- chest X-ray:
- bilateral lower lobe alveolar infiltrates
- pleural effusion is common
- nodules & cavitation may occur
Complications
- pneumonic plague is 100% lethal if not treated within 24 hours
Differential diagnosis
Management
- treatment for 7-10 days with
- streptomycin or gentamicin (1st line[4]), or
- doxycycline, or
- ciprofloxacin, levofloxacin, moxifloxacin[5]
- patients must be isolated for 48 hours until it is determined that disease has not progressed to pneumonic form
- post-exposure prophylaxis
- doxycycline, or ciprofloxacin, levofloxacin for 7 days
Notes
- potential agent of bioterrorism[7]
- British nursery rhyme[15]
