Salmonella Infection – Diagnosis and Treatment
Diagnosis
Doctors suspect a salmonella infection when someone has symptoms like diarrhea, abdominal pain, and fever, especially after eating food linked to outbreaks. They confirm the infection by doing a stool test to look for the bacteria in the feces.
If there are signs of dehydration, bacteremia, or possible typhoid fever, doctors check blood samples. Laboratory testing helps guide treatment.
Common Diagnosis Steps:
| Step | Purpose |
|---|---|
| Review of symptoms | Identify signs of infection |
| Stool sample test | Detect Salmonella in feces |
| Blood test | Check for spread (bacteremia) |
If problems like reactive arthritis appear later, follow-up care may be needed. In certain cases, doctors may also test for antibiotic resistance to determine the best treatment plan.
People with weakened immune systems, infants, and older adults may require additional evaluation to prevent complications.
Treatment
Replacing Lost Fluids and Minerals
Salmonella infection often causes diarrhea and vomiting, which can make the body lose important fluids and electrolytes. To prevent dehydration, drink extra fluids such as water, clear broths, or oral rehydration solutions.
Children and older adults have a higher risk for severe dehydration. If someone becomes very dehydrated, doctors may give fluids through a vein (IV) at a hospital.
Signs of dehydration include:
- Dry mouth or tongue
- Few or no tears when crying
- Dizziness or weakness
- Less urine than usual
Medicines Used in Care
Doctors may suggest anti-diarrheal drugs such as loperamide. These drugs can lower cramping but may slow down how fast the body gets rid of the bacteria.
Antibiotics are sometimes used if the infection spreads outside the intestines, is very severe, or the person has problems with their immune system.
Most healthy people do not need antibiotics. Using antibiotics for mild salmonella can raise the chance of a relapse or let the person spread the bacteria for a longer time.
Self-Care
To handle symptoms at home, stay hydrated. Drinking water often helps replace fluids lost from vomiting or diarrhea.
| Do | Avoid |
|---|---|
| Drink plenty of water | Sugary sodas |
| Use oral solutions | Full-strength fruit juices |
| Eat light meals | Heavy, greasy foods |
Avoid drinks like full-strength juice and soda, which can make diarrhea worse. For babies and young kids, use oral rehydration solutions. These products are easy to find without a prescription and contain the right mix of water and salts.

- What treatment options are there?
- Are there dietary or activity restrictions?
- Should a specialist be involved?
- Is there a generic drug that would work?
You may want to bring someone with you. Another person can remember important details or questions you might miss. Bringing a written list to your appointment helps make sure nothing is forgotten.
Here is a short checklist:

| Questions | Helps address your concerns |
| Support person | Extra help with information and support |
Questions Your Provider Might Ask
During your visit, your health care provider will ask about:
- When your symptoms started
- How often you have vomiting or diarrhea
They may also ask for details about your vomit or stool, such as the presence of blood or mucus. Your provider will want to know if you have a fever.
They will ask about recent travel or any possible exposure risks. Clear answers help your provider understand your situation. This information guides the next steps for your care.
