occurrence of a disease within a specific area or region in excess of its normal level.
a term used to describe a disease that is rare then suddenly affects more people than usually expected
affecting or tending to affect a disproportionately large numbers of individuals within a population, community, or region at the same time.
the condition in which a disease spreads rapidly through a community in which that disease is normally not present or is present at a low level.
Disease that spreads rapidly and infects many people in a community or area (usually within a short time frame). The number of cases indicating presence of an epidemic will vary according to the infectious agent, size and type of population exposed, previous experience or lack of exposure to the disease, and time and place of occurrence; epidemicity is thus relative to usual frequency of the disease in the same area, among the specified population, at the same season of the year. A single case of a communicable disease long absent from a population or the first invasion by a disease not previously recognized in that area requires immediate reporting and epidemiologic investigation; two cases of such a disease associated in time and place are sufficient evidence of transmission to be considered an epidemic. (See Report of a Disease and Zoonosis).
the occurrence in a community or region of cases of an illness (or outbreak) with a frequency clearly in excess of normal expectancy.
a disease that spreads rapidly through a demographic segment of the human population, such as everyone in a given geographic area, or a similar population segment; also refers to a disease whose incidence is beyond what is expected.
The spread of an infectious disease through a population or geographic area.

1. affecting a large proportion of the population at the same time. 2. a sudden outbreak of disease which affects a large proportion of a population at the same time. Compare endemic.

A large outbreak of a contagious disease.
The occurrence in a community or region of cases of disease clearly in excess of normal expectancy. The community or region, and the period in which the cases occur, are specified directly. The number of cases indicating the presence of an epidemic varies according to the agent, size and type of population exposed, previous experience or lack of exposure to the disease, and time and place of occurrence. An epidemic is relative to usual frequency of the disease in the same area, among the specified population, at the same season of the year.
a disease that occurs above the expected level among individuals in a population

An outbreak of a disease that spreads within a community. A pandemic is an epidemic over a vast area – it usually refers to an outbreak that affects several countries.
an outbreak of disease such that for a limited period a significantly greater number of persons in a community or region suffer from it than is normally the case. Thus an epidemic is a temporary increase in incidence. Its extent and duration are determined by the interaction of such variables as the nature and infectivity of the casual agent, its mode of transmission and the degree of preexisting and newly acquired immunity.
The outbreak and occurrence of a disease that afflicts a large number of people at once in a given area. The disease may either be carried in from somewhere else, or be a sudden though short term increase of an endemic disease. (See also Endemic and Pandemic).

The common definition of an MRSA epidemic is: 1) several (e.g. three or more nosocomially-acquired) cases which are epidemiologically associated by person, time, or place, or 2) a substantial increase in number of cases in a facility endemic for MRSA. Each facility must decide the criterion to define an outbreak.
A disease that spreads rapidly through a part of the human population--such as everyone in a given geographic area, a military base, school, or village--or everyone of a certain age or sex, such as the children or women of a region. Epidemic diseases can be spread from person to person or from a contaminated source such as food or water.

Affecting, or tending to affect, many individuals within a population, community, or region, at the same time; excessively prevalent
In epidemiology, an epidemic (from Greek epi- upon + demos people) is a disease that appears as new cases in a given human population, during a given period, at a rate that substantially exceeds what is "expected", based on recent experience (the number of new cases in the population during a specified period of time is called the "incidence rate"). (An epizootic is the same thing but for an animal population.) Also see Steward's "The Next Global Threat: Pandemic Influenza".
