Prevalance of Plague:
In the U.S., 1
to 40 cases reported annually (avg = 13 cases) by western states, 1971-1995
Worldwide, 2861
cases reported by 10 countries to WHO in 1995
SEQUELAE
- Rare, consequences
of disseminated intravascular coagulation, lung damage
- Mortality 50-90%
if untreated; 15% when diagnosed and treated
COSTS
TRANSMISSION
- Flea-borne, from
infected rodents to humans
- Direct contact
with infected tissues or fluids from handling sick or dead animals
- Respiratory droplets
from cats and humans with pneumonic plague
RESERVOIRS
- Primarily wild
rodents in U.S. (especially rock squirrels, ground squirrels, prairie
dogs, other burrowing rodents)
- Commensal rats
may be important elsewhere
RISK GROUPS
- In the U.S., persons
exposed to rodent fleas, wild rodents, or other susceptible animals
in enzootic areas of western states
- Most cases occur
in southwestern states of NM, AZ, CO, and in CA
- Highest rates in
Native Americans, especially Navajos; other risk groups: hunters; veterinarians
and pet owners handling infected cats; campers or hikers entering areas
with outbreaks of animal plague
SURVEILLANCE
- National Notifiable
Disease Surveillance System (NNDSS) for animal plague surveillance,
for reports of human cases, and laboratory testing of fleas, animal
tissues and serum specimens, and serosurveys of carnivores
- CDC, Fort Collins,
is a WHO Collaborating Center for Reference and Research on Plague Control,
and reports all human plague cases in the U.S. to WHO
OPPORTUNITIES
- Increased self-sufficiency
of state and county public health labs
- Expanded active
surveillance through carnivore serosurveys and application of geographic
information systems (GIS) to surveillance programs
- Increased education
of public and health professionals
- Collaborative applied
research on plague prevention and control with other federal, state,
and local health agencies, including application of GIS to surveillance
RESEARCH
- Ecology-based prevention
and control strategies
- Improved diagnostic
reagents and methods
- Development of
potential vaccine candidates
- Risk factor identification
using landscape ecology and epidemiology

About statistics:
This page presents a variety of statistics about Plague.
The term 'prevalence' of Plague usually refers to the estimated population
of people who are managing Plague at any given time.
The term 'incidence' of Plague refers to the annual diagnosis rate,
or the number of new cases of Plague diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
For more information see about prevalence and incidence statistics.
