In short
Typhoid fever is a serious disease caused by Salmonella bacteria that is not common in the United States but frequently occurs in developing countries. Salmonella infections can also cause symptoms such as fever, diarrhea, abdominal cramps, headache, and possible nausea, vomiting, and loss of appetite. While most people get better without treatment, the infection can be more serious in older adults, infants, and people with chronic health problems, or if the bacteria enter the bloodstream.

Description
Salmonella is the name of a group of bacteria. In the United States, it is a common cause of foodborne illness.
Salmonella occurs in raw poultry, eggs, beef, and sometimes on unwashed fruit and vegetables. You also can get infected after handling pets, especially reptiles like snakes, turtles, and lizards.
Symptoms include:
- Fever
- Diarrhea
- Abdominal cramps
- Headache
- Possible nausea, vomiting, and loss of appetite
Symptoms usually last 4-7 days. Your health care provider diagnoses the infection with a stool test. Most people get better without treatment. Infection can be more serious in older adults, infants, and people with chronic health problems. If Salmonella gets into the bloodstream, it can be serious. The usual treatment is antibiotics.
Typhoid fever, a more serious disease caused by Salmonella, is not common in the United States. It frequently occurs in developing countries.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.
Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.
What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.
Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
In an emergency, call 112 (or your local emergency number). Do not delay seeking medical help because of something you read here.
