A certain strain of salmonella bacteria causes it. Typhoid fever is rare in places where few people carry the bacteria. It's also rare in places that treat water to kill germs and manage human waste well. That's why typhoid fever is rare in the United States.</p> <p>Most people in the U.S. who get typhoid fever get it during travel to other countries. Africa and South Asia have the highest rates of typhoid fever.</p> <p>Antibiotics can treat typhoid fever, but some antibiotics no longer work against the typhoid fever bacteria. This is called antibiotic resistance. Without treatment, there is a small chance of death from typhoid fever complications. Vaccines that protect against typhoid fever help lower the risk of getting the condition.</p> </section> </conbodydiv> </conbody> </hecsConcept> <hecsConcept contentType="http://ontology.mayo.edu/ContentCategories/Symptoms" policy="did:mcid:PDkv3FCzsA4FPiHVvT1zRc" reviewedOn="2023-01-28T06:00:00.000-06:00" workId="did:mcid:YBT8az2iDGxBdtj23CSADJ:2026-10-08" xml:lang="en"> <title>symptoms typhoid fever consumer</title> <titlealts> <titleSimple> <ph keyref="titleSimple-symptoms">Symptoms</ph> </titleSimple> </titlealts> <conbody> <conbodydiv platform="richtext"> <section> <p>Symptoms are likely to start slowly, often showing up 1 to 3 weeks after contact with the bacteria.</p> </section> <section> <title>Early illness</title> <p>Early symptoms may include:</p> <ul> <li>Lasting fever that starts low and rises during the day.

You might get the vaccine if you live where typhoid fever is common. Or you might get the vaccine if you plan to travel to a place where the risk is high.</p> </section> <section> <title>Vaccines</title> <p>There are two vaccines in the United States. They come in the form of:</p> <ul> <li>A single shot you get at least one week before travel. People age 2 and older can take this. It lasts two years.</li> <li>Four capsules you take by mouth every other day. People age 6 and older can take this form. It lasts up to 5 years.</li> </ul> <p>The vaccine doesn't completely protect you from typhoid fever. So follow these guidelines when in high-risk areas:</p> <ul> <li> <b>Wash your hands often and well.</b> Use hot, soapy water. Wash before eating or making food and after using the toilet or changing a diaper. Carry an alcohol-based hand sanitizer for when you don't have soap and water.</li> <li> <b>Don't use water that isn't safe.</b> In places where typhoid fever is common, drinking water often has the bacteria that causes it. So drink only bottled water or canned or bottled carbonated drinks, wine or beer. Ask for drinks without ice. Use bottled water to brush your teeth and try not to swallow water in the shower.</li> <li> <b>Don't eat raw fruits and vegetables.</b> Because raw produce may have been washed in tainted water, don't eat fruits and vegetables that you can't peel, especially lettuce. To be safe, don't eat any raw foods.</li> <li> <b>Choose hot foods.</b> Don't eat food that's stored or served at room temperature. Cooked, steaming hot foods may be less risky than other foods.</li> </ul> </section> <section> <title>Don't infect others</title> <p>If you're recovering from typhoid fever, you can help keep others safe. Besides washing your hands well and often, do the following:</p> <ul> <li> <b>Take your antibiotics.</b> Do as your healthcare professional tells you when taking your antibiotics. Take all the pills in the prescription.</li> <li> <b>Don't handle food.</b> Don't make food for others until your healthcare professional says it's safe. If you're a food or healthcare worker, you may need to take a test to show that you've stopped shedding typhoid bacteria before you return to work.</li> </ul> </section> </conbodydiv> </conbody> </hecsConcept> <hecsConcept contentType="http://ontology.mayo.edu/ContentCategories/Diagnosis" policy="did:mcid:PDkv3FCzsA4FPiHVvT1zRc" reviewedOn="2023-01-28T06:00:00.000-06:00" workId="did:mcid:PRXRsqk676DHCuX98AgGKp:2026-10-08" xml:lang="en"> <title>diagnosis typhoid fever consumer</title> <titlealts> <titleSimple> <ph keyref="titleSimple-diagnosis">Diagnosis</ph> </titleSimple> </titlealts> <conbody> <conbodydiv platform="richtext"> <section> <p>Your healthcare professional may suspect typhoid fever based on your symptoms and your medical and travel history.
