The outbreak can be visually described with a chart showing the number of persons who became ill each week. This chart is called an epidemic curve or epi curve. Illnesses that occurred after November 23, 2009 may not yet be reported due to the time it takes between when a person becomes ill and when the illness is reported. This takes an average of 2 to 3 weeks. Please see the Salmonella Outbreak Investigations: Timeline for Reporting Cases for more details.
