Reservoirs
Describe four ways that humans can be carriers
A symptomatic, chronic, passive, convulsive, incubation
Explain what t means to be a carrier of infectious disease
Can pass on to someone else
convalescent
Coming down from sickness however still infected
Highly communicable
Contagious
pandemic
Flu's- across continents
Koch's Postulates
How to study agent that cause disease
Source
Individual or object from which an infection is acquired
Chronic
Long term illness, always sick
Asymtomatic
No symptoms, Mary Millon
Biological
Participates in pathogens life cycle, infected with the pathogen, transmitted by bites, defecation.. mosquito
Reservoirs
Primary habitat in natural world from which a pathogen originates.
Epidemic
all of a sudden in large amounts
What is epidemiology and medically important about carriers in the population
are they contagious and can they cause an epidemic
Vectors
can be biological (infected) or mechanical (not infected)
Reservoirs can be
carriers, vectors or non living
Medical a sepsis
developed to reduce non socomial infections
Anatomical Barriers: Mucous Membrane
digestive, urinary, and eyes
Sporadic
every once in a while
vertical transmission
from parent to offspring
Non communicable
host acquires infectious agent, from self or non living resivior (soil, food)
communicable
infected host transmits an infectious agent to another host, receiving host must become infected
nonsocomial infection
infection acquired in a hospital
Soil
non living reservoir that transmits bacteria, protozoa, helminths, and fungi.
Mechanical
not part of pathogens life cycle, not infected with pathogen, housefly or cockroach.. on the body
Anatomical barriers: skin
outermost layer, Keratin, skin glands
transmit developmental stage
ova and larve
Passive
someone/something who came in contact with pathogen
endemic
specific to geographical location
Transmit resistant stages
spores and cycts
universal precautions
standards set for handling patients and body substances
Epidemiology
study of disease in a population through frequency and distribution data
etiology
the study of agent that causes disease
Horizontal transmission
through population from one infected person to another
