Every year, Salmonella is estimated [PDF - 1 page] to cause one million foodborne illnesses in the United States, with 19,000 hospitalizations and 380 deaths. Most persons infected with Salmonella develop diarrhea, fever, and abdominal cramps 12 to 72 hours after infection.
The illness usually lasts 4 to 7 days, and most persons recover without treatment. However, in some persons, the diarrhea may be so severe that the patient needs to be hospitalized.
Public health scientists have tracked Salmonella infections in the United States since 1962. By identifying the structures on the bacteria’s surfaces, scientists can classify the many types of Salmonella into serotypes.
An Atlas of Salmonella in the United States, 1968-2011[PDF - 248 pages] is the first-of-its-kind report that charts over 40 years of laboratory-confirmed surveillance data on 32 Salmonella serotypes. The report includes analyses by age, sex, season, and geography, down to the county level. This is the first time CDC has posted these data online in a downloadable format.
