What To Know About Typhoid Vaccines For Traveling

What Is Typhoid And How Is It Transmitted

Typhoid is an illness caused by a bacteria called Salmonella enterica serotype Typhi, which is the same bacteria that causes food poisoning.  It is most commonly found in underdeveloped countries where tap water is poorly sanitized. Typhoid is transmitted through contaminated food and water. Therefore, infected stools coming in contact with the water supply can further spread the disease. The bacteria can survive for several weeks in sewers. 

Examples of countries most affected by this illness are Egypt, India, Pakistan, and the continents of South America, Asia, and AfricaThe disease can be diagnosed through a blood culture and stool culture. 

People sick with typhoid fever might start to see symptoms 1-2 weeks after being infected and then be ill for around 3-4 weeks. 

Common symptoms of typhoid fever are: 

  • High fever that that gradually increases each day (as high as 40 Celsius)

  • Extreme fatigue
  • Generalized pain and aches
