Effectiveness of Hand Scrubbing & Epidemiology

QuestionAnswer
microorganisms that are more or less permanent normal microbiota
microbes that are present only for days or weeks transient microbiota
the single most important procedure for preventing nosocomial infections hand washing
organism that harbors the pathogen host
can be spread either directly or indirectly from one host to another communicable diseases
disease that cannot be transmitted from one host to another (coccidioides immitis) noncommunicable diseases
science that deals with when and where diseases occur and how they are transmitted in the human population epidemiology
diseases that are constantly present in the population (like pneumonia) Endemic diseases

contact with contaminated inanimate objects also called fomites
insects and other arthropods that carry pathogens vectors
insects carry a pathogen on their feet and may transfer the pathogen to a person's food mechanical transmission
transmission of a disease by an arthropod's bite (Anopheles mosquito) biological transmission
continual source of an infection reservoir
humans who harbor pathogens but don't show any signs of disease carriers
compiles data on the incidence of a disease and is method of transmission and tries to locate the source of infection to decrease the incidence epidemiologist
gives a visual display of the outbreak's magnitude and time trend epidemic curve
