control
Compliance and enforcement intervention strategies can be divided into what two
groups? - Correct Answer-1. Those designed to achieve immediate on-site correction.
2. Those designed to achieve long-term compliance.
What is a Standard Operating Procedure (SOP)? - Correct Answer-A standard
operation procedure (SOP) is a written process that provides consistent guidance to
employees within an organization as to how they should properly complete a given task
in a uniform manner. It provides detailed steps and details the tools necessary to
complete the task.
What is Malfeasance? - Correct Answer-The doing of an act that is wrongful and that is
known to be wholly unauthorized by the official.
,What is Misfeasance? - Correct Answer-The doing of an authorized act in an
unauthorized manner.
What is Nonfeasance? - Correct Answer-The failure to perform an official duty without
sufficient excuse.
What are the two main types of epidemiological studies that can be used in an
epidemiological investigation? - Correct Answer-Descriptive and Analytical.
Active Immunity - Correct Answer-Results when exposure to a disease organism
triggers the immune system to produce antibodies to that disease. Active immunity can
be acquired through natural immunity or vaccine-induced immunity
Passive Immunity - Correct Answer-When a person is given antibodies to a disease
rather than producing them through his or her own immune system.
Agent (biology/epi) - Correct Answer-A factor (e.g., a microorganism or chemical
substance) or form of energy whose presence, excessive presence, or in the case of
deficiency diseases, relative absence is essential for the occurrence of a disease or
other adverse health outcome.
Mode of Transmission - Correct Answer-The manner in which an agent is transmitted
from its reservoir to a susceptible host.
Carrier - Correct Answer-A person or animal that harbors the infectious agent for a
disease and can transmit it to others, but does not demonstrate signs of the disease. A
carrier can be asymptomatic (never indicate signs of the disease) or can display signs
of the disease only during the incubation period, convalescence, or postconvalescence.
The period of being a carrier can be short (a transient carrier) or long (a chronic carrier).
Morbidity - Correct Answer-(disease) Any departure, subjective or objective, from a
state of physiological or psychological health and well-being.
Mortality - Correct Answer-Death
Demographic Information - Correct Answer-Personal characteristics of a person or
group (e.g., age, sex, race/ethnicity, residence, and occupation) demographic
information is used in descriptive epidemiology to characterize patients or populations.
Pandemic - Correct Answer-An epidemic occurring over a widespread area (multiple
countries or continents) and usually affecting a substantial proportion of the population.
Endemic - Correct Answer-The constant presence of an agent or health condition within
a given geographic area or population; can also refer to the usual prevalence of an
agent or condition.
, Epidemic - Correct Answer-The occurrence of more cases of disease, injury, or other
health condition than expected in a given area or among a specific group of persons
during a particular period. Usually, the cases are presumed to have a common cause or
to be related to one another in some way.
Frequency - Correct Answer-The amount or number of occurrences of an attribute or
health outcome among a population.
Portal of Entry - Correct Answer-A pathway into the host that gives an agent access to
tissue that will allow it to multiply or act.
Prevalence - Correct Answer-The number or proportion of cases or events or attributes
among a given population.
Host - Correct Answer-A person or other living organism that is susceptible to or
harbors an infectious agent under natural conditions.
Reservoir - Correct Answer-The habitat in which an infectious agent normally lives,
grows, and multiplies, which can include humans, animals, or the environment.
Descriptive Epidemiology - Correct Answer-The aspect of epidemiology concerned with
organizing and summarizing data regarding the persons affected (e.g., the
characteristics of those who became ill), time (e.g., when they become ill), and place
(e.g., where they might have been exposed to the cause of illness).
Applied Epidemiology - Correct Answer-The application or practice of epidemiology to
control and prevent health problems.
Lag Phase - Correct Answer-The period of time between the introduction of a
microorganism into a culture medium and the time it begins to increase exponentially
Physical factors - Correct Answer-Examples include geology and climate, harmful
substances, such as air pollution or proximity to toxic sites (the focus of classic
environmental epidemiology); access to various health-related resources (e.g., healthy
or unhealthy foods, recreational resources, medical care); and community design and
the "built environment" (e.g., land use mix, street connectivity, transportation systems).
Log phase (growth phase) - Correct Answer-The period of growth of a population of
cells (as of a microorganism) in a culture medium during which numbers increase
exponentially and which is represented by a part of the growth curve that is a straight
line segment if the logarithm of numbers is plotted against time
Equal Protection - Correct Answer-A right guaranteed by the Bill of Rights requiring the
comparable treatment of people and situations. It guides governmental actions in not
burdening or benefiting people differentially without reasonable grounds.
