Typhoid Fever Surveillance System

Appendix III: CDC's Surveillance Systems for

Foodborne Disease

The Typhoid Fever Surveillance System was established in 1962 to collect

Typhoid Fever

detailed information about all cases of Salmonella typhi. State health

Surveillance System

department officials are asked to complete a typhoid fever surveillance

report form when a laboratory confirms a case of typhoid fever. The form

collects demographic information about each case, as well as information

about patients' international travel and vaccination history, and the

antibiotic susceptibility of isolates. This information is especially

important for developing travel advisories, vaccination recommendations,

and treatment guidelines.

Geographic Scope: National.

Pathogen: Salmonella typhi.

Cases Reported: In 1999, 115 cases were reported to this system.

Data Sources: Local or state health department officials complete the

typhoid fever surveillance report forms and submit them to CDC's

Foodborne and Diarrheal Diseases Branch. In addition, cases of

laboratory-confirmed Salmonella typhi infection are reported to CDC

through the Public Health Laboratory Information System as part of the

National Salmonella Surveillance System, accompanied by limited

information on patient age and sex, and on the clinical source of the

isolate.
