Salmonella
Non-typhoidal salmonellosis; typhoid/paratyphoid require separate assessment
The short answer
Salmonella is a group of bacteria. This guide mainly addresses non-typhoidal diarrhoeal illness; typhoid and paratyphoid require separate assessment.
Transmission and timing
Sources include contaminated food or water and animal or stool contact. Travel and shared-meal histories help assessment.
CDC ↗Symptoms and risk groups
Diarrhoea, fever and cramps may occur. Infants, older adults and immunocompromised people need closer assessment for severe infection.
CDC ↗CDC ↗When to seek help
Seek care for severe dehydration, bloody diarrhoea or marked deterioration. Infection can spread beyond the intestine in some patients.
CDC ↗For life-threatening symptoms, severe breathing difficulty or altered consciousness, call your local emergency number (112 in Türkiye).
What does the test show?
Culture is important for diagnosis. After a positive molecular test, culture may support susceptibility assessment and public-health investigation.
CDC ↗Care and treatment approach
Many patients recover with fluid support; not every positive Salmonella result requires antibiotics. Treatment decisions are individualized for severe or high-risk illness.
CDC ↗Prevention and everyday life
Separate raw and cooked foods and refrigerate perishable food appropriately. Wash hands after contact with animals and their environments.
CDC ↗Clinical assessment note
Record travel, invasive-disease risk and resistance considerations. Evaluate suspected typhoid separately from non-typhoidal gastroenteritis.
CDC ↗Bring a question to your appointment
How are we distinguishing non-typhoidal infection from typhoid?
International evidence, local decisions
Each source’s country is identified. Vaccine access, reimbursement, isolation and reporting rules vary. Use current guidance and your clinician’s advice in your country; English does not imply UK or US eligibility.
