Bichat guidelines for the clinical management of plague and bioterrorism-related plague
1Task Force on Biological and Chemical Agent Threats, Public Health Directorate, European Commission, Luxembourg.
Abstract:
Yersinia pestis appears to be a good candidate agent for a bioterrorist attack. The use of an aerosolised form of this agent could cause an explosive outbreak of primary plague pneumonia. The bacteria could be used also to infect the rodent population and then spread to humans. Most of the therapeutic guidelines suggest using gentamicin or streptomycin as first line therapy with ciprofloxacin as optional treatment. Persons who come in contact with patients with pneumonic plague should receive antibiotic prophylaxis with doxycycline or ciprofloxacin for 7 days. Prevention of human-to-human transmission via patients with plague pneumonia can be achieved by implementing standard isolation procedures until at least 4 days of antibiotic treatment have been administered. For the other clinical types of the disease, patients should be isolated for the first 48 hours after the initiation of treatment.
Insights
Yersinia pestis, a bioterrorism threat, can cause plague pneumonia outbreaks. Early antibiotic treatment and prophylaxis are key to preventing transmission and managing potential bioterrorism events.
Area of Science:
- Microbiology
- Public Health
- Infectious Diseases
Background:
- Yersinia pestis is a potential bioterrorism agent.
- Aerosolized Yersinia pestis can cause explosive outbreaks of plague pneumonia.
- The bacteria can also spread from rodents to humans.
Purpose of the Study:
- To outline therapeutic guidelines for Yersinia pestis infections.
- To define antibiotic prophylaxis strategies for exposed individuals.
- To recommend isolation procedures for preventing disease transmission.
Main Methods:
- Review of existing therapeutic guidelines for plague.
- Analysis of recommended antibiotic treatments (gentamicin, streptomycin, ciprofloxacin).
- Evaluation of antibiotic prophylaxis (doxycycline, ciprofloxacin) and isolation protocols.
Main Results:
- Gentamicin or streptomycin are first-line therapies; ciprofloxacin is an alternative.
- Antibiotic prophylaxis for contacts includes doxycycline or ciprofloxacin for 7 days.
- Isolation periods vary: 4 days for pneumonic plague, 48 hours for other forms.
Conclusions:
- Yersinia pestis poses a significant bioterrorism risk, particularly via aerosolized forms causing pneumonic plague.
- Prompt and appropriate antibiotic treatment and prophylaxis are crucial for managing Yersinia pestis infections and preventing spread.
- Effective isolation strategies are essential to control human-to-human transmission of plague.
