Question	Answer
The entry of a microbial agent into a higher-order host and its multiplication within the host.	Infection
The measure of the number of organisms infecting an individual.	Intencity
A disease that is constantly present in a population.	Endemic disease
New cases of a disease. Commonly used to describe the actual number of new cases.	Incidence
The occurrence of a disease at a greater level than what would normally be expected.	Epidemic
The proportion of a population that develops the outcome of interest in a specific time period.	Cumulative incidence
The time between initial infection (entry of The disease into susceptible host) and the onset of clinical disease(symptoms).	Incubation period
When a lower organism lives on an external surface of an other (usually higher) organism.	Infestation
The ability of an organism to invade and multiply within a host. It is the proportion of exposures that result in infection.	Infectivity
A generic term to describe the genetic, phenotypic, behavioural, life style, environmental factors (or potential causes) being studied in relation to an outcome of interest.	Exposure
The period between the first detectable signs of a disease and the overt symptoms that normally lead to diagnosis.	Lead time
A measure of cumulative incidence often used for an outbreak that occurs over a relativity short time period.	Attack rate
A mixing or muddling of effects that can occur when the relationship we are interested in is confused by the effect of something else.	Confounding
The theoretical point during the development of a disease after which the disease process is irreversible and treatment will confer little or no benefit.	Critical point
When something is consistent across different groups it is	Homogeneous
When something varies across different groups it is	Heterogeneous
