About typhoid fever

What is typhoid fever?

Typhoid fever is a disease caused by a type of bacteria called Salmonella Typhi.1 Typhoid fever can be a severe and even life-threatening illness.1 An estimated 11 to 21 million cases of typhoid fever occur worldwide each year.1

How do I get typhoid fever?

Typhoid fever is spread through contaminated food or water and by person-to-person contact.1 For example, you can get typhoid fever if you eat or drink something that has been touched by someone who is still getting rid of the Salmonella Typhi bacteria in their feces (stools) – especially if they haven’t washed their hands well after using the bathroom.1 You can also contract typhoid fever if sewage that has the bacteria in it gets into something you eat or drink, or if it gets into the water used to rinse food that you eat raw.1

What are the symptoms of typhoid fever?

Common symptoms of typhoid fever include loss of appetite, headache, weakness, stomach pain, and constipation or diarrhea.2,3 In severe cases, stomach bleeding, brain damage, and death may occur.3 The symptoms of typhoid fever may vary from person to person. And remember, you can still pass on typhoid fever to others even after your symptoms are gone.2

Where am I most at risk for typhoid fever?

Typhoid fever is commonly found in regions of the world where water and food may be unsafe.3,4 Travelers to South Asia are at greatest risk for typhoid fever. Africa, Latin America, and Southeast Asia are other high-risk regions for infection, while East Asia and the Caribbean are lower-risk regions.3

The Centers for Disease Control and Prevention (CDC) recommends vaccination for people traveling to places where typhoid fever is common.5

How can I help protect myself against typhoid fever?

CDC recommends a typhoid fever vaccination for people traveling to places where typhoid fever is common.5 Talk to your healthcare provider or pharmacist about getting vaccinated before you travel. Want to find a provider in your area? Click here.

Immunization is one of the best ways to help protect you and your family from typhoid fever.5

Typhoid fever vaccines are not 100% effective. Always practice safe eating and drinking habits to help prevent infection.5

You should follow the CDC guidelines for safe eating and drinking overseas, where typhoid fever is common. These precautions include4:

  • Eating food that is cooked and served hot
  • Drinking bottled water
  • Avoiding ice
  • Avoiding raw vegetables and fruits that cannot be peeled

How is typhoid fever treated?

Typhoid fever is treated with antibiotics2; however, according to data reported in 2017, 74% of Salmonella Typhi infections are resistant to one of the most commonly used antibiotics, so treatment options are diminishing.6
