Investigation Announcement: Multistate Outbreak of Human Typhoid Fever Infections Associated with Frozen Mamey Fruit Pulp

Infections with the Outbreak Strain of Salmonella Typhi, by Week of Illness Onset (n=9 for whom information was reported as of 08/12/10)

An epi curve (graph) showing infections with an outbreak strain of Salmonella by date of illness.

The outbreak can be visually described with a chart showing the number of persons who became ill each day. This chart is called an epidemic curve or epi curve. Illnesses that occurred after May 30, 2010, might not yet be reported due to the time it takes between when a person becomes ill, when laboratory testing is completed, when the diagnosis is confirmed, and when the illness is reported. For typhoid fever outbreaks, this takes an average of 8-10 weeks. This delay is denoted by the gray box on the epi curve.
