Recommendations for the control of Yersinia pestis infections. Recommendations from the CDC
Abstract:
Yersinia pestis, the etiologic agent of plague, is endemic in the western United States; 105 cases were reported between 1970 and 1979. Plague may manifest in one of three clinical forms; bubonic, septicemic, or pneumonic. Bubonic and septicemic plague represent relatively little risk for human-to-human transmission to contacts, although heavily infected secretions, such as drainage from a bubo, pose a theoretical risk, especially if they are aerosolized from a syringe during diagnohree clinical forms; bubonic, septicemic, or penumonic. Bubonic and septicemic plague represent relatively little risk for human-to-human transmission to contacts, although heavily infected secretions, such as drainage from a bubo, pose a theoretical risk, especially if they are aerosolized from a syringe during diagnohree clinical forms; bubonic, septicemic, or penumonic. Bubonic and septicemic plague represent relatively little risk for human-to-human transmission to contacts, although heavily infected secretions, such as drainage from a bubo, pose a theoretical risk, especially if they are aerosolized from a syringe during diagnostic aspirations. Pneumonic plague may be highly contagious to contacts and poses a greater risk. The Plague Branch, Center for Disease Control recommends that all patients with plague be placed in strict isolation for the first 48 hours of treatment because of the possibility that pneumonia may supervene. If it does not, wound and skin precautions are adequate for the duration of hospitalization. Untreated plague pneumonia is an epidemiologic emergency. All contacts must be identified promptly and those with face-to-face exposure should receive abortive antibiotic therapy. All contacts should be under surveillance, with twice-daily temperature checks, for seven days.
Insights
Pneumonic plague is highly contagious and requires strict isolation for patients. Close contacts need prompt identification and antibiotic treatment to prevent further spread of this Yersinia pestis infection.
Area of Science:
- Infectious Diseases
- Epidemiology
- Microbiology
Background:
- Yersinia pestis causes plague, endemic in the western US with 105 cases reported 1970-1979.
- Plague presents as bubonic, septicemic, or pneumonic forms.
- Bubonic and septicemic plague have limited human-to-human transmission risk.
Purpose of the Study:
- To outline the transmission risks and recommended management for different forms of plague.
- To emphasize the public health importance of pneumonic plague.
- To provide guidance on isolation and contact management for plague patients.
Main Methods:
- Review of plague clinical presentations and transmission dynamics.
- Analysis of case reports and epidemiological data.
- Formulation of public health recommendations based on disease characteristics.
Main Results:
- Pneumonic plague poses a significant risk of human-to-human transmission.
- Bubonic/septicemic plague has minimal transmission risk, with theoretical risk from aerosolized secretions.
- Early treatment and isolation are critical for managing plague, especially the pneumonic form.
Conclusions:
- Patients with plague require strict isolation for the first 48 hours of treatment.
- Pneumonic plague necessitates prompt identification and antibiotic therapy for all contacts.
- Surveillance of contacts with twice-daily temperature checks for seven days is recommended.
