Constructing a Line listing
A line listing is an information table describing persons associated with an outbreak. It
includes basic descriptive epidemiological information and orients the outbreak by time, place
and person. Information often includes identifying information (name, phone number, county of
residence), demographic information (date of birth, sex, occupation); date and time of onset
and recovery; symptoms experienced and other important factors (microbiology, hospitalisations,
diagnosis, potential exposures). It is a unique record for each individual with a unique
identifier and helps to avoid confusion with multiple versions. It can be updated as the
investigation develops and allows regular, automated, computerised analysis.
Using information from a line listing
Frequency distributions of demographic factors such as age, race and sex provide further
information about potential outbreak exposures and risk of disease.
Frequency distributions of potential risk factors such as occupation, recreational activities
and places visited may provide insights into the outbreak source.
Geographic Information Systems can be used to plot locations such
as residence or employment locations. This information can provide clues to potential exposure
patterns in the outbreak. If the overall population varies in different areas on the map, the
investigator should plot the attack rate in each area (instead of number of cases) because
plotting only the number of cases can be misleading.
