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
