This website focuses on the types of Salmonella that most commonly cause diarrheal illness. Other types of Salmonella – Salmonella Typhi and Salmonella Paratyphi – cause typhoid fever and paratyphoid fever.
CDC estimates Salmonella bacteria cause about 1.35 million infections, 26,500 hospitalizations, and 420 deaths in the United States every year. Food is the source for most of these illnesses.
- Most people who get ill from Salmonella have diarrhea, fever, and stomach cramps.
- Symptoms usually begin 6 hours to 6 days after infection and last 4 to 7 days.
- Most people recover without specific treatment and should not take antibiotics. Antibiotics are typically used only to treat people who have severe illness or who are at risk for it.
- Some people’s illness may be so severe that they need to be hospitalized.
