How Common is Salmonella Infection?
CDC estimates that approximately 1.2 million illnesses and approximately 450 deaths occur due to non-typhoidal Salmonella annually in the United States2. Read more key Salmonella statistics.
There are many different kinds of Salmonella bacteria. Salmonella serotype Typhimurium [PDF - 15 pages] and Salmonella serotype Enteritidis [PDF - 15 pages] are the most common in the United States3. Salmonella infections are more common in the summer than winter. Learn more about Salmonella serotypes.
Who is at Highest Risk for Salmonella Infection?
Children are at the highest risk for Salmonella infection. Children under the age of 5 [PDF - 36 pages] have higher rates of Salmonella infection than any other age group3. Young children, older adults, and people with weakened immune systems are the most likely to have severe infections4.
Are there Long-Term Consequences to a Salmonella Infection?
People with diarrhea due to a Salmonella infection usually recover completely, although it may be several months before their bowel habits are entirely normal.
A small number of people with Salmonella develop pain in their joints. This is called reactive arthritis. Reactive arthritis can last for months or years and can lead to chronic arthritis, which can be difficult to treat1. Antibiotic treatment of the initial Salmonella infection does not make a difference in whether or not the person develops arthritis1. People with reactive arthritis can also develop irritation of the eyes and painful urination5.
